What are the five defenses required by the substation and distribution room?

The "five preventions" of the substation and distribution room are fireproof, waterproof, lightning, snowproof, and small animal proof. "One pass" means to keep the ventilation well. The concept of "five defenses" in the power system refers to:

1. Prevent mis-division and closing of circuit breakers.

2. Prevent the disconnecting switch from dividing and closing with load.

3. Prevent live hanging (closing) grounding wire (grounding switch).

4. Prevent power transmission with ground wire, that is, prevent circuit breaker (isolation switch) with grounding wire (grounding switch).

5. Prevent mistakenly entering the live interval.

Five defenses. That is, fireproof, waterproof, lightning-proof, snow-proof, and anti-small animals. "One pass" means to keep the ventilation well.

Substation and distribution room. Equipment room for voltage rise and fall and power distribution. Generally, there are high and low voltage cabinets, transformers, DC panels and other complete sets of electrical equipment.

Power distribution room: refers to the voltage level of 10kV and below.

The facilities of the equipment are divided into high-voltage distribution room and low-voltage distribution room. The high-voltage distribution room generally refers to the 6kV 10kV high-voltage switch room; The low-voltage distribution room generally refers to the 400V distribution room for the transformer line of the 10kV or 35kV station.

Fireproof, waterproof, leakproof, snowproof, and small animal proof.

Five prevention: fireproof, waterproof, lightning, snowproof, and small animal prevention. "One pass" means to keep the ventilation well.

Legal analysis: The five defenses of the power distribution room refer to 1Prevent mis-division and mis-closing of circuit breakers; 2

Prevent the load from pulling and closing the disconnector or the contact of the handcart; 3.Prevent live hanging (closing) grounding wire (grounding switch); 4.Prevent the circuit breaker (disconnecting switch) from being closed with a grounding wire (grounding switch); 5.

Prevent inadvertent entry into the live interval.

Legal basis: "Xiangsun Law of the People's Republic of China on Production Safety" Article 62 The local people at or above the county level shall, according to the production safety situation within their respective administrative areas, organize relevant departments to conduct strict inspections of production and business operation units that are prone to major production safety accidents within their administrative areas in accordance with the division of responsibilities. The emergency management department shall, in accordance with the requirements of classified and hierarchical supervision and management, formulate an annual supervision and inspection plan for production safety, and conduct supervision and inspection in accordance with the annual supervision and inspection plan.

The five defenses of the distribution room refer to 1Prevent mis-division and mis-closing of circuit breakers; 2.Prevent the load from pulling and closing the disconnector or the contact of the handcart; 3.

Prevent live hanging (closing) grounding wire (grounding switch); 4.Prevent the circuit breaker (disconnecting switch) with grounding wire (section rotten ground knife switch); 5.Prevent inadvertent entry into the live interval.

1. What are the applicable conditions for the preservation of traffic accident property?

1.The application for interim measures must be made by the parties.

2.Sponsorship is required.

3.The purpose of property preservation is to prevent irreparable damage to their lawful rights and interests or to avoid the judgment that may be unenforceable or difficult to enforce due to the conduct of one of the parties or other reasons.

4.The scope of property preservation is limited to the scope of the request or property related to the case.

2. Safety precautions for falling objects.

1.Helmet. When entering dangerous places according to regulations, you must wear a safety helmet that meets the safety standards and fasten the hat strap to prevent the hat from falling off and losing its protective effect when the person falls.

2.Safety belt. All personnel who work in the air above 2m must wear qualified safety belts. If there is no condition for wearing safety belts in the suspended work site, measures should be formulated to set up safety ropes and safety railings for workers to hang safety belts.

3.Safety nets. Where there is no outer frame protection operation point, must be set up at a height of 4m above the ground to set up a fixed safety net, high-rise construction should also be every four layers of no drawbacks to install a fixed safety net, and at the same time set up a layer of safety net with the wall layer by layer.

Article 62 of the Law of the People's Republic of China on the Safety of Dry Burning Production: Local people at or above the county level shall, according to the safety production situation within their respective administrative areas, organize relevant departments to conduct strict inspections on production and business operation units that are prone to major production safety accidents within their administrative areas. The emergency management department shall, in accordance with the requirements of classified and hierarchical supervision and management, formulate an annual supervision and inspection plan for production safety, and conduct supervision and inspection in accordance with the annual supervision and inspection plan, and shall deal with potential accidents in a timely manner.

Summary. The "five preventions" of the substation and distribution room are fireproof, waterproof, lightning, snowproof, and small animal proof. "One pass" means to keep the ventilation well.

What does the substation and distribution room refer to when it is required to achieve "five prevention and one pass"?

Hello, I'm glad to answer for you It takes some time to type, please wait.

The "five preventions" of the substation and distribution room are fireproof, waterproof, lightning, snowproof, and small animal proof. "One pass" means to keep the ventilation well.

The concept of "five defenses" in the power system refers to: 1. Prevent misdivision and closing circuit breakers. 2. Prevent the disconnecting switch from dividing and closing with load.

3. Prevent live hanging (closing) grounding wire (grounding switch). 4. Prevent power transmission with ground wire, that is, prevent the belt grounding wire (grounding switch) from closing the circuit and sliding lead coarse device (isolating the opening and opening of the radical off). 5. Prevent the letter from entering the live interval by mistake.

Do you have any more questions? You can also pay attention to the answer to the world lord Oh If you have any questions in the future, you can consult directly, if you are satisfied with my reply, please give me a thumbs up after the point is over.

1.The air temperature and humidity of the substation and distribution room shall meet the requirements of DL T 593 and GB T 24274:

a) The upper limit of the ambient air temperature shall not be higher than 40 and its average temperature shall not exceed 35 in a 24-hour period;

b) At a maximum temperature of 40, its relative humidity must not exceed 50%. At lower temperatures, a large relative humidity is allowed, but the average humidity of the phase Luzhou socks measured within 24 hours does not exceed 95%, and the average monthly relative humidity does not exceed 90%, taking into account the possibility of occasional moderate condensation due to temperature changes.

2.Insulating rubber pads should be laid in the operation area and maintenance channel of transformers, high-voltage distribution devices and low-voltage distribution devices in the substation and distribution room.

3.Low-voltage temporary power supplies, hand-held power tools, etc. should be powered by TN-S, and residual current action protection devices should be adopted.

4.The normal lighting and trace cavity emergency lighting system should be in good condition.

5.The continuous illumination time of the evacuation indicator light should be greater than 30min.

6.For the room equipped with the power distribution equipment that produces toxic gases and asphyxiating gases, an exhaust device should be installed in the parts of the room that are prone to accumulate gases in the event of an accident.

7.The layout of indoor substation and distribution devices, safety clearance, passages and fences shall meet the requirements of GB 50053, GB 50054, GB 50059, GB 50060 and other national standards.

Five prevention: fireproof, waterproof, lightning, snowproof, and small animal prevention. "One pass" means to keep the ventilation well.
