Why is it said that electrical equipment is always considered to have electricity until it is verifi

Electrical equipment is considered to have electricity before it is verified that there is no electricity, which is to protect the safety of life and avoid mistaking the feeling that there is no electricity and causing electric shock.

Before the electrical system and electrical equipment are put into use, in order to determine whether there are quality problems in installation or manufacturing, and to determine whether the newly installed or operating electrical equipment can be put into operation normally, the insulation performance, electrical characteristics and mechanical properties of each electrical equipment unit in the electrical system shall be tested and verified item by item in accordance with the relevant provisions of the standards, regulations and specifications.

Through these tests and verifications, defects, errors and quality problems of electrical equipment can be found and eliminated in a timely manner during manufacturing and installation, ensuring that electrical systems and electrical equipment can be put into operation normally.

Electrical equipment is considered to be powered for safety purposes until it is verified that there is no electricity. Before it is verified that there is no electricity, it will be treated as electricity, and it is forbidden to close randomly, prohibit touching, and prohibit construction.

There are two situations before the electrical equipment is not verified to be without electricity:

1. If there is electricity, if there is electricity, you must pay attention to safety and not move around.

2. There is no electricity, but this lack of electricity is just a guess, not a verification. If you treat it as if you don't have electricity, you can move it, but if you guess it wrong, if you have electricity, you will have an injury accident.

How can any electrical equipment be considered without electricity until it is verified? （）a.No electricity. b.Maybe there's electricity.

c.There is an electric banquet sale.

d.Maybe there is no electricity.

Correct answer: c

Electrical equipment refers to all electrical equipment, including transformers, power lines, etc., these equipment are high-power electrical equipment, and there are clear terms in the electricity regulations: any electrical equipment is treated in accordance with electricity before it is verified, and it is forbidden to touch and switch the gate indiscriminately!

The voltage of large electrical equipment is very high, and if it is touched in an unclear situation, it will cause immeasurable damage, and the management of electricity is quite strict, and the electrical equipment will only be stricter. There is no electrical equipment with unclear conditions, there must be conspicuous warning signs, signs, electrical equipment is composed of power supply and electrical equipment, so the use of electrical equipment must be carried out in strict accordance with the safety manual.

Electrical equipment should first do a good job of insulation, large transformers and old noisy power lines in the natural environment do not slow to avoid damp or wet, absolute insulation is crucial, high voltage environment will form a negative high voltage environment when wet, the surrounding land and items will be with high voltage disturbance with congratulatory electricity, at this time if someone mistakenly enters or touches it will be a disaster, in a high temperature environment, electrical equipment ventilation should also be dealt with.

Summary. Any electrical equipment should be considered to be in a state of electricity until it has been verified that there is no electricity. This means that proper safety measures must be taken to ensure the safety of personnel before any repairs, overhauls or operations are carried out.

These measures include, but are not limited to:1Disconnect the power supply:

You must disconnect the power supply before proceeding with any operation. This can be achieved by turning off the circuit breaker or pulling the plug. 2.

Use safety tools: Before performing any operation, you must use appropriate safety tools such as insulated gloves, insulated boots, insulated tools, etc. 3.

Grounding: Before proceeding with any operation, you must ensure that the device is grounded. This can be achieved by using a grounding wire or a grounding rod.

4.Perform an inspection: Before proceeding with any operation, you must perform an electrical inspection to ensure that the device has been powered off.

This can be achieved by using a voltmeter or a test pen.
