Household multifunctional safety protection distribution box

Abstract

The invention discloses a household multifunctional safety protection distribution box which comprises a distribution box shell. A comprehensive digital display alarm is arranged on the upper side of a panel of the distribution box shell, a smoke sensor probe is arranged on the left lower side of the panel on the front side of the distribution box shell, an alarm buzzer is arranged on the middle lower side of the panel on the front side of the distribution box shell, a switch contact output socket is arranged on the right lower side of the panel on the front side of the distribution box shell, a temperature detection probe is arranged inside the distribution box shell, backup protectors are arranged on the leftmost side of the inside of the distribution box shell, power lightning protection devices are arranged on the right side of the backup protectors, an overvoltage and undervoltage protector is arranged on the right side of the power lightning protection devices, a leakage protector main switch is arranged on the right side of the overvoltage and undervoltage protector, and circuit breaker branch switches are arranged on the right side of the leakage protector main switch. The household multifunctional safety protection distribution box has the advantage that a comprehensive household electricity safety protection effect can be realized by the power distribution box with monitoring and protection devices.

Description

technical field [0001] The invention relates to the fields of lightning protection and household power distribution, in particular to a protective distribution box, in particular to a household multifunctional safety protection distribution box. Background technique [0002] With the advancement of science and technology and the popularization and application of new electronic devices and technologies, people pay more and more attention to the safety protection and disaster protection of household electricity. As we all know, our family life is inseparable from various electrical appliances, communication and control equipment, so a safe and reliable power supply system and protective measures must be used to ensure power supply. In ordinary residential buildings, the power supply department connects the single-phase AC power line to the electrical switch box indoors. The box is equipped with a circuit breaker master switch, leakage protector and multiple shunt circuit brea...

Problems solved by technology

However, the reality is that the voltage of the external power grid often fluctuates, especially in the vast rural areas and industrially developed areas. The voltage drop of the power grid during the peak and valley of the electricity is very large. If the household appliances are forced to run when the voltage is under voltage, or withstand the high voltage when the voltage is over, it will affect the service life and even cause damage; moreover, the power line may also be damaged. Lightning attack and interference, especially in spring, summer and autumn in coastal areas, frequent lightning will cause instantaneous high voltage and super large current on the power line. If the induced lightning invades the indoor distribution line, it will definitely cause damage to household appliances; There are some other reasons, such as the aging of the power supply equipment, the power line being broken by strong wind or foreign objects, and the power line being stolen or damaged, which may cause the open circuit of the neutral line, which may also cause a sudden change in the power supply voltage; Excessive loads cause heating of lines, accidental fires, etc., all of which will cause harm to household electricity and bring instability to home safety. Therefore, ordinary household electrical switch boxes cannot play an effective warning and protective role.
