What are the hazards of high temperature weather to power equipment and preventive measures?

Harm of high temperature weather to power equipment and preventive measures;

Since the summer, the weather has been hot, the frequency of household appliances has increased, the electricity consumption has increased greatly, the load of electrical lines has increased, and some transformers and meter boxes have frequently caught fire. The hidden danger of this kind of transformer can not be ignored.

In order to prevent this kind of fire, units and residents should conduct a comprehensive inspection of houses and surrounding wires in time.

A, found that the wire seriously aging should be replaced in time, fuse can't be replaced by copper wire, aluminum wire, try to cut off the power supply before going out.

Second, private access is strictly prohibited; One more reminder: don't use electrical appliances for a long time. For example, the TV can't be charged all the time. Unplug the power plug in time after seeing it, so as not to cause an electrical fire.

When this kind of fire happens, the corresponding countermeasures:

A, check whether the transformer circuit breaker has tripped, if not, immediately disconnect the power supply of each side of the circuit breaker and then put out the fire.

Second, when using dry powder or carbon dioxide fire extinguisher to put out the fire, you can also quickly cover the fire source with a wet carpet or quilt to keep the distribution room ventilated and avoid casualties. Also dial 1 19.

Third, beware of power safety accidents.

When it is wet in summer, the insulation material will lose its insulation performance when it is wet, which makes people sweat easily and increases the chance of electric shock.

Electrical equipment should have grounding and zero protection, install leakage protection devices, and the workplace must be kept dry and clean. Cut off the power supply of maintenance equipment, put up a warning sign "No closing, someone is working", and lock the power supply when possible. When moving electrical equipment, first cut off the power supply and protect the wires. Insulation aging, short circuit, overload, loose joints, dust accumulation, humidity, and electrical appliances close to flammable materials are all likely to cause fires.

Electricians must receive special training and hold relevant certificates. Operators must wear insulating protective articles, and personnel engaged in high-voltage live working should wear shielding clothing. Dry powder and carbon dioxide fire extinguisher should be used when electrical equipment is on fire.
