A household multifunctional safety protection distribution box

Abstract

The present invention is a household multifunctional safety protection distribution box, comprising a distribution box shell, a comprehensive digital display alarm device is provided above the panel of the distribution box shell, and a A smoke sensor probe, an alarm buzzer is provided on the middle and lower side of the front panel of the distribution box housing, a switch contact output socket is provided on the lower right side of the front panel of the distribution box housing, and an internal device of the distribution box housing There is a temperature detection probe, a backup protector is installed on the leftmost side of the distribution box shell, a power surge protector is installed on the right side of the backup protector, an overvoltage and undervoltage protector is installed on the right side of the power surge protector, and overvoltage and undervoltage protection The main switch of the leakage protector is installed on the right side of the device, and the circuit breaker shunt switch is installed on the right side of the main switch of the leakage protector. The power distribution box after using these monitoring and protection devices has played an all-round safety protection for household electricity consumption.

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 break...

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.
