Safe electricity consumption is closely related to people's life and property safety, and should be paid great attention to. In order to enhance the awareness of power safety, the knowledge of safe power use needs to be mastered.

Timely investigation of hidden dangers of electricity can effectively prevent fire accidents. Is there an electrical device that can do that?

1. Knowledge of safe electricity use

1. Why is the lighting switch connected to the firewire?

If the lighting switch is installed on the neutral line, although the lamp is not bright when it is disconnected, the phase line of the lamp head is still connected, and people think that the lamp is not bright, it will mistakenly think that it is in a state of power failure. In fact, the voltage to the ground at each point on the lamp is still 220 volts of dangerous voltage. If people touch these parts that are actually charged when the light is off, it can cause an electric shock. Therefore, all kinds of lighting switches or single-phase small-capacity electrical equipment switches, only connected to the fire line, in order to ensure safety.

2, single-phase three-hole socket how to install?

Generally, single-phase electrical equipment, especially mobile electrical equipment, should use three-core plugs and matching three-hole sockets. The three-hole socket has a special protection zero (ground) jack, in the use of zero protection, some people often only in the socket at the bottom of the hole wiring pile head and the zero wire into the socket directly connected, which is extremely dangerous. In case the neutral line of the power supply is disconnected, or the fire (phase) line and neutral line of the power supply are reversed, the metal part such as the shell will also bring the same voltage as the power supply, which will lead to electric shock.

Therefore, the special grounding jack should be connected with the special protection grounding wire when wiring. When using zero protection, the zero line should be specially attracted from the power supply end, and do not use the zero line introduced into the socket nearby.

3. Why is plastic insulated wire strictly forbidden to be buried in the wall?

1. After the plastic insulated wire is used for a long time, the plastic will age and crack, and the insulation level will be greatly reduced. When the line is overloaded or short-circuited, it is easier to accelerate the damage of the insulation.

2. Once the wall is damp, it will cause a large area of leakage, endangering personal safety.

3. The plastic insulated wire is directly buried, which is not conducive to the repair and maintenance of the line.

4, how to prevent burning of household appliances?

The rated voltage of commonly used household appliances is 220 volts, and the normal power supply voltage is about 220 volts. When the power supply line, if the power supply voltage caused by natural disasters such as lightning strikes instantaneous rise, three-phase load imbalance, household line disrepair occurs zero line, or due to human wrong wiring and other reasons caused by the phase voltage rise, it will increase the current resulting in overheating and burning of household appliances.

To prevent the burning of household appliances, it is necessary to start from the following aspects:

First, the electrical equipment should be disconnected as far as possible when not in use;

The second is to transform the old and disrepair of the household line;

The third is to install a leakage protector with overvoltage protection.

2. Avoid electrical safety accidents

There are many devices and equipment for safe electricity consumption, but there is still no way to effectively prevent various electrical fires.

Therefore, it also promotes the emergence of smart electricity, and intelligent circuit breakers are one of them.

How do intelligent circuit breakers use electricity safely?

Intelligent circuit breaker shell material is made of high quality impact resistance, high flame retardant material, with bimetal plate overload reverse time trip protection, and short circuit instantaneous trip protection. The contact is made of 95% silver alloy material, the conductor is made of high-quality T2 copper, and the arc extinguishing chamber is made of red steel insulation board and nickel-plated steel plate.

High breaking capacity, continuous and stable protection of home core power safety. Real-time monitoring of current, voltage, temperature, power, power factor, electricity, undervoltage, overload, overcurrent, overtemperature, ignition, short circuit and other faults alarm or tripping, prevent electrical fire.

Automatically get iot standard time and set timing control. Remote operation through mobile APP or PC-side cloud platform.

Intelligent circuit breakers can also help people automatically detect whether the leakage protection function is normal, if there is an abnormal automatic warning, so as to avoid various electrical injuries caused by the failure of the leakage protection device!

Monitor the back-end electrical equipment in real time, limit the current through AI algorithm recommendation, and freely set the circuit on-off time to ensure safety and realize energy saving.

Through the intelligent gateway and smart home device interconnection, easy intelligent linkage and scene setting, to ensure the safety of users while using electricity, to achieve intelligent control of equipment, energy control, to meet the needs of users.
