What are the precautions for the operation of live cleaning of power and electrical equipment?

When cleaning power equipment with electricity, it is necessary to formulate a thorough and solid cleaning plan in advance according to different cleaning objects and different environmental conditions.

2.Although the cleaning agent is safer and more reliable than water cleaning, the safety regulations for live work must still be strictly observed; In order to ensure the implementation of safety regulations, organizational measures and on-site monitoring must be carried out.

3.Pay attention to keep the distance between the person and the nozzle and the charged body, in line with the distance and the minimum liquid column length stipulated in the electric power "safety regulations".

4.Check that the cleaning agent used should be a good insulating liquid.

5.When cleaning the overhanging insulator, tensile insulator string and porcelain cross arm, it should be cleaned sequentially from the side of the wire to the side of the cross arm; When cleaning the pillar insulator and insulating porcelain sleeve, it should be cleaned from the bottom up.

6.When cleaning the insulator, attention should be paid to the wind direction, the downwind side must be cleaned first, and then the upwind side, and the insulators arranged in the upper and lower layers should be cleaned first and then the upper layer should be cleaned; Also pay attention to the cleaning angle.

7.The flushing angle refers to the angle between the liquid column and the central shaft of the equipment to be cleaned, and the flushing angle should be maintained at 90 degrees, and if the conditions do not allow, it can be maintained at 60 degrees; When cleaning tensile insulator strings, a projection angle of 30-40 degrees can be used.

8.In the same substation, it is not advisable to clean different phases at the same time, and the liquid column should not be crossed by two phases to prevent short circuits.

9.In the process of cleaning, due to the change of voltage, sparks may occur in areas with high voltages, so do not aim the liquid column directly at the sparks.

10.When cleaning with electricity, people must maintain reliable insulation from person to ground.

11.When the wind is strong, the air humidity is high (more than 60%), the rainy weather and the temperature difference between the cleaning agent and the insulator is too large, it is not suitable for live cleaning operations.

12.Before cleaning, it is necessary to confirm whether the equipment is well insulated, and it is generally not possible to clean insulators with zero or low values and porcelain cracks.

13.When cleaning the operating mechanism of the circuit breaker, it should be noted that the grease of the mechanical transmission part cannot be cleaned, or it should be added immediately after the cleaning is completed in consultation with the user.

14.When cleaning the isolated knife switch blade, it should be paid attention to whether the blade contact is good, and the hydraulic pressure should not be too large.

15.When cleaning transformers, current transformers, and voltage transformers, it is necessary to observe whether there is oil leakage, and if so, the liquid column cannot be sprayed directly on the oil seepage.

When using live cleaning agent for electric power and electrical equipment, it is necessary to pay attention to the fact that clean water cannot be used for cleaning during the cleaning process, and it is necessary to ensure that the cleaning agent is free of flash point to ensure the safety of operation. ENIENT EC0102 is recommended, which has no flash point and is the first choice for use as a cleaning agent for electrical and electrical equipment.

Modern safety technology maintenance - live cleaning, is a change after traditional cleaning, and it has been continuously expanded and studied. Electrified cleaning insulation lubrication maintenance technology system (firstly, the primary equipment is mechanically cleaned and brushed live, followed by the use of electrical mechanical equipment cleaning agent for high-pressure jet cleaning of the cleaned primary equipment and secondary equipment, the use of precision electronic instrument cleaning agent for live cleaning of the monitoring system, and finally the cleaning of the after.

The first and second equipment uses leakage protection fluid for insulation maintenance) This set of technical systems can solve the problems of equipment insulation decline caused by environmental pollution.

Jiangyin has promising electricity.

Live maintenance is mainly for long-term operation, not suitable or even can not run the power outage network communication and power electrical and traffic controller and other equipment services, equipment operation in the continuous accumulation of static electricity and dust, to the safe operation of the equipment buried many hidden dangers, traditional products, technology and services can not be completely solved, for this pain point of the company's technical team after directional research, developed a number of products, technologies and services with independent intellectual property rights.

Cleaning principle. The decontamination method of the product is a pure physical method of nano molecule decomposition, packaging and then carried away by liquid pressure, which can efficiently remove dust, oil, carbon stains, salts, moisture, metal dust and other pollutants attached to the equipment under the normal operation of the equipment. After use, it can prolong the service life of the equipment, reduce the loss of the equipment, and avoid the phenomenon of short circuit ignition and poor heat dissipation of the equipment.

The maximum applicable voltage of power and electrical equipment cleaning agent is 500kV, and the cleaning agent of network communication equipment can remove static electricity of equipment.

After the equipment is cleaned with electricity, a layer of nano protective film can be formed by using a series of live curing products and protection processes, which can isolate the erosion of pollutants such as moisture, salt spray, dust, and oil in the environment and ensure the safe operation of the equipment.

With the continuous upgrading and transformation of modern industry, the performance and precision requirements of workpieces and parts are getting higher and higher,..

2.Which equipment can be cleaned with electricity The equipment that can be cleaned with electricity is mainly divided into two categories: precision electronic equipment and electrical mechanical equipment.

3.How to ensure the safety of live cleaning The first condition for the implementation of live cleaning is the safety issue, and it is the belt to ensure the safety of people and equipment.

4.Cleaning and maintenance of communication equipment Usually, due to air pollution and the limitation of environmental conditions in the communication equipment room, the operation of the equipment air supply system.

5.Common cleaning methods and methods 1Offline cleaning disconnects circuit boards and single components from the device according to the prescribed procedure.

To be honest, if I usually look at the washing machine in the house if it is too dirty, I will clean it with electricity...

Jiangyin has a power to provide you with a reply.

Oil, dust, sand, smoke, moisture and other pollution to electrical equipment directly affect the heat dissipation and function of electronic components, shorten their service life.

Oxidation and corrosion of metal parts of electromechanical, power distribution and electrical equipment by acid gas and salt will undoubtedly significantly reduce their service life and cause contact insulation.

The resistance rises, accelerates the aging of the equipment, and causes the temperature of the contact to rise, which will cause a flash fire and cause a short circuit or short circuit, and destroy the operation of the whole set of equipment lines.

It even led to a catastrophe.

i Damage to the function of electrical equipment by metal dust, static electricity and charged particles.

In the process of long-term continuous operation of precision electronic equipment, due to various comprehensive pollutants such as dust, metal salts, and oil pollution floating in the atmosphere, through physical adsorption, the gravity sedimentation of particles deposited on the surface of precision electronic equipment and the environmental conditions of the communication equipment room, the operation of the equipment air supply system, the transformation and decoration of the computer room, etc., the communication equipment under long-term continuous operation will be seriously polluted. The heat dissipation capacity of precision electronic equipment is reduced, which affects its operation quality and reliability. These dust, oil, moisture, salt, oxidation, corrosive gases, etc., cause comprehensive pollution to the circuits in the equipment, resulting in additional microcircuit effects and corrosion retardation effects of the equipment; The electromagnetic field distribution in the normal operation of communication equipment, the accumulation of friction in the air supply system for a long time, etc., cause the accumulation of static electricity, which together form the two major root causes of soft faults in communication equipment, which cause poor contact of precision electronic equipment to varying degrees, and the increase of impedance reduction, leakage, short circuit, obstacle rate, bit error, bad board, etc., resulting in the increase of soft failure rate such as line energy loss, weakening of transmission signal, instability of transmission rate and quality, and the heat dissipation capacity of seriously polluted equipment will also decrease. It affects the traffic connection rate and communication quality.
