What is the content of the five defenses?

Question 1: What do you mean by five points for attention? "Five precautions" usually refers to the abbreviation of five misoperation prevention functions for high-voltage switchgear to ensure personal safety, which is one of the important measures for power safety.

The content of "Five Preventions" is 1, to prevent the circuit breaker from being divided and closed by mistake. 2, to prevent the load points, isolating switch. 3, to prevent live hanging (close) ground wire (grounding switch). 4, to prevent the use of grounding wire transmission. 5, to prevent the wrong charged interval.

Question 2: The concept of "five defenses" refers to the five defenses in the power system:

(1) Prevent the circuit breaker from being opened or closed by mistake.

(2) Prevent the on-load disconnector.

(3) to prevent live hanging (close) grounding wire (grounding switch).

(4) Prevent grounding wire (earthing switch) and circuit breaker (disconnector).

(5) to prevent the wrong charged interval.

Realizing the "five precautions" function of electricity has become one of the important measures for safe production of electric power. With the continuous development of power grid and the continuous updating of technology, the anti-misoperation device is also constantly improving and perfecting. The design principle of anti-misoperation device is that all high-voltage electrical equipment that may cause misoperation should be equipped with anti-misoperation device and corresponding anti-misoperation electrical blocking circuit.

Question 3: What are the five points for attention? First, five points for attention in electricity consumption:

1, to prevent misoperation, circuit breaker.

2, to prevent the load points, isolating switch.

3, to prevent live hanging (close) ground wire (grounding switch).

4, to prevent the use of grounding wire transmission.

5, to prevent the wrong charged interval.

Second, the five precautions for a safe life:

1, fire protection

2, anti-theft

Step 3 prevent robbery

4. Anti-fraud

5. Prevent accidents.

Question 4: What do the five safety precautions mean? 1. Five electrical safety precautions:

Isolating switch for preventing on-load opening and closing.

Prevent misoperation of circuit breakers, load switches and contactors.

When the grounding switch is in the closed position, prevent the grounding switch from closing the circuit breaker and the load switch.

Prevent the grounding switch from closing by mistake when it is live.

Prevent from entering a charged room by mistake.

2. Five precautions for safe production in summer:

Heatstroke prevention, flood control, electric shock prevention, lightning protection and flood control.

3. Five precautions for safe production in winter:

Fire prevention, anti-freezing, anti-skid, anti-fog, anti-falling from high altitude.

4. Five precautions for construction site safety: heatstroke prevention and cooling, fire safety, electric shock prevention, gas safety, flood prevention and typhoon safety.

5, life safety five prevention:

Theft prevention, fraud prevention, robbery prevention, accident prevention and fire prevention.

Question 5: What does the five-prevention system mean? 1, prevent load sharing and close isolation. (The disconnector cannot be operated when the circuit breaker, load switch and contactor are closed. )

2, to prevent the wrong points, wrong circuit breaker, load switch, contactor. (Only when the operating instructions correspond to the operating equipment can the equipment be operated on * * * *).

3. Prevent the grounding switch from closing the circuit breaker and load switch in the closed position. (Only when the grounding switch is off, the disconnector can be closed or the handcart can enter the working position, and the circuit breaker and load sharing switch can be operated and closed. )

4, to prevent the wrong grounding switch when charged. (Only when the circuit breaker is disconnected, can you operate the isolating switch or the handcart retreat from the working position to the test position and close the grounding switch. )

5, to prevent straying into the charged room. Only when the car is not electrified can you open the door and enter the car. )

Question 6: What are the five electrical precautions? Five preventive measures in power system refer to:

(1) Prevent the circuit breaker from being opened or closed by mistake.

(2) Prevent the on-load disconnector.

(3) to prevent live hanging (close) grounding wire (grounding switch).

(4) Prevent grounding wire (earthing switch) and circuit breaker (disconnector).

(5) to prevent the wrong charged interval.

My sister has done it before. It's absolutely correct.

Question 7: What are the "five precautions" required by high-voltage distribution equipment? The contents of five prevention functions of high-voltage distribution equipment are:

1) prevents loading points. Close the isolating switch;

2) Prevent misoperation. Close the circuit breaker;

3) To prevent live grounding wire (or grounding breaker);

4) Prevent the disconnector from being grounded.

5) Prevent from entering the charging interval by mistake.

In addition to the electric shock protection function, high-voltage distribution equipment should also meet the requirements of five protection functions. This is to prevent electric shock casualties, electrical fires and electrical equipment damage accidents, and to ensure the safety of power systems and power users. In order to meet the five-prevention function, a locking device for realizing the five-prevention function is generally installed in high-voltage distribution equipment.

Question 8: What are the five safety precautions 1 and five electrical safety precautions?
