Abstract

The invention discloses an electric equipment protector. The electric equipment protector comprises a first normally-closed contact which is connected with a load and an AC220V voltage and a second normally-closed contact, wherein the second normally-closed contact is connected with a 10kiloohm potentiometer; the 10kiloohm potentiometer is connected with a comparator and a mono-stable time delay controller in parallel; the comparator is connected with a normal work LED indicator lamp and a fault flicker LED alarm lamp; the mono-stable time delay controller is connected with a relay; a rectifier bridge block is connected between the 10kiloohm potentiometer and the AC220V voltage. The electric equipment protector can be directly mounted in electric sockets and switches, can be integrally manufactured during the production, and is more attractive and elegant during the mounting. The protection system of the electric equipment protector has various protection functions such as overcurrent protection and leakage protection, is convenient to mount without any other equipment, low in cost and wide in market prospect to ensure that every household can afford, and can be used for ensuring the personal safety and the safety of the electric equipment.

Description

technical field [0001] The invention relates to the technical field of a protector for electrical equipment, in particular to a device connected to an electrical circuit, which enables on-line detection of electrical equipment and electrical circuits and protection of electrical equipment when the electrical equipment is working And electrical equipment protectors for electrical lines. Background technique [0002] At present, it is well known that in general household electricity and offices, office buildings and other places where electricity is used, there are many cases of random plugging and connection of electrical equipment, but there are relatively few personnel with electrical expertise, so many places use electricity is not standardized, There are many blindness, but in the process of decoration and power lines, many installations are not standardized, and there are many cases of cutting corners, which reduces the actual load bearing capacity of power lines, but in...
