How to select electric power preventive test equipment?

Preventive test is an important part of the operation and maintenance of power equipment, and it is also one of the effective means to ensure the safe operation of power equipment. In order to detect hidden dangers of equipment in operation and prevent accidents or equipment damage, inspection, testing or monitoring of equipment is carried out, including tests carried out by taking oil or gas samples. With the increase of test projects, the required test equipment will be very large, at this time a power test vehicle can handle most of the power test projects.

Wuhan Guodian Xigao GDSY-9000 electric power preventive test vehicle can be equipped with various configurations according to user requirements, which can meet most of the power preventive test projects on site. This car is designed and developed according to the "DL T596-1996 Power Equipment Preventive Test Regulations" and other equipment test requirements, for the handover test and periodic preventive test of power equipment before operation in major substations across the country, and has been widely used in the power industry.

The car adopts digital monitoring and network communication of intelligent intensive power test vehicle, used in substations, power stations and other power supply departments of centralized testing, power outage repair and other occasions with special requirements. In addition, all the test devices and equipment that need to be used are placed in a special test vehicle, which can be directly transported to the test site, and can be transported back to the warehouse as a whole after the test, which is very convenient.

Standard Test Device Section:

Optional test device section:

At the same time, the electric preventive test vehicle also has a complete auxiliary system. The vehicle is equipped with GPS system, wireless dispatching communication system, expert diagnosis system, equipment management system, centralized control system, vehicle shockproof unit, monitoring unit, singing unit, storage unit, safety warning unit, lighting unit, etc., which can provide strong support and help for field tests, which is very worthy of everyone's choice!

What is the precautionary nature of electricity? Test equipment. If you don't have a connotation, you still choose. Affected by the sales volume is relatively high.

What I just shot is the prevention of five experiments, which is to do leakage, experiments and breakdown experiments.

If you want to do the anti-performance test in the high-voltage distribution room, you can go to the test manual and read the test manual, or you can know what test he is going to do when he is doing the test.

All equipment in the distribution room needs to be tested.

1.Bus insulation test, 2Circuit breaker test.

3.Isolation knife switch test.

4. Current transformer, voltage transformer test.

5.Surge arrester test.

Preventive test is an important part of the operation and maintenance of power equipment, and is one of the effective means to ensure the safe operation of the power system. Musen Electric can do preventive tests. Through the test, grasp the changes in the insulation performance of the equipment, find the internal defects in time, and take corresponding measures for maintenance and overhaul to ensure the safe and reliable operation of the equipment.

The purpose of the insulation test is to check the reliability of the insulation performance of the equipment under the action of long-term rated voltage, and even under the action of external overvoltage, harmful discharge will not occur, resulting in insulation breakdown.

The preventive test of electric power is a diagnostic inspection item before the equipment has no problems, and it is one of the effective means to ensure the safe operation of power equipment.

In addition to preventive tests, there are also handover tests, travel tests, etc.

Preventive test is an important part of the operation and maintenance of power equipment, and is one of the effective means to ensure the safe operation of power equipment. Over the years, the high-voltage power equipment of the power sector and large industrial and mining enterprises has basically been tested in accordance with the requirements of the "Preventive Test Regulations for Power Equipment" (hereinafter referred to as the "Regulations") issued by the former Ministry of Electric Power, which plays an important role in timely discovering and diagnosing equipment defects.

The preventive test is to check whether the equipment in operation has insulation defects and other defects in accordance with the cycle specified in the preventive test procedure for power equipment "DL T596-2005" after the electrical equipment is put into operation.

"Preventive Test Regulations for Power Equipment (DL T596-1996 Revised Instructions)" is a revised description of DL T 596-1996 "Preventive Test Regulations for Power Equipment".

The book will be based on the 1985 version of the regulations on the basis of the revision process, the problems encountered in the revision and the handling opinions, chapter by chapter article by article to explain, so the "power equipment preventive test procedures (DL T596-1996 revision instructions)" can be called the implementation of DL T596-1996 important reference book.

Explanation of terms: power equipment (power system) mainly includes power generation equipment and power supply equipment, power generation equipment is mainly power station boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc., power supply equipment is mainly transmission lines of various voltage levels, transformers, contactors, etc.

The power secondary equipment is a system, not only the device itself, such as AC, DC, control loops, etc., because some circuits do not have monitoring means, the equipment status can not be judged by real-time technical analysis. Therefore, in terms of the application status of electrical secondary equipment, strictly speaking, most of the protection does not have the conditions for condition maintenance.

There are serious defects in the planned maintenance system of most of the power equipment in the power system, such as frequent temporary maintenance, insufficient maintenance or overmaintenance, blind maintenance, etc., which makes countries around the world spend huge amounts of money on equipment maintenance every year.

The preventive test of electrical equipment refers to the electrical personnel through the electrical test, before the equipment is put into operation or during the operation to understand the insulation of the equipment, so that the fault can be found and dealt with accurately and timely in the early stage of development.

The practice of electric power production proves that the inspection and test of electrical equipment according to the regulations is one of the important measures to prevent problems before they occur and ensure the safe and economical operation of the power system, and the so-called "preventive test" is named after it.

DC withstand voltage test, DC resistance test, variable ratio test, etc.

AC withstand voltage test, DC withstand voltage test, DC resistance test, variable ratio test, loop resistance test, switch test test, dielectric loss angle test, insulation test, grounding resistance test, cable and wire insulation wire diameter test, load test (current) air conditioner wind speed, pressure, temperature, humidity, noise test, lighting brightness test.

In the process of operation, electrical equipment is affected by the electric field force, the operating temperature and air humidity, corrosive gas and other factors, the insulation condition will continue to deteriorate, which is a normal decline phenomenon, as long as it meets the operating conditions specified by the equipment manufacturer, it can reach the safe use period.
