Problems solved by technology

[0002] At present, electricity leakage often occurs in many household lines, but it is difficult for users to find out the location of the leakage in a short time, so it is impossible to provide emergency power supply without affecting the safety of use.
This is also an important reason why many users do not install leakage protectors, but choose ordinary miniature circuit breakers. For example, some electrical equipment itself has a leakage current greater than 30mA, such as groundwater pumps, which must be replaced with ordinary miniature circuit breakers because they cannot supply power normally. Leading to restrictions on the scope of use of leakage protectors

Embodiment Construction

[0014] The present invention provides a household leakage protector that can be switched on with leakage current, refer to figure 1 and figure 2 , including an upper cover 1 and a base; the upper cover 1 includes a test jump button 2, a reset button 3, an operating handle 4 and a communication interface 8; the base includes a CPU controller 7, a trip unit 5 and a current transformer 6; The test jump key 2, the current transformer 6, the release device 5, and the communication interface 8 are electrically connected to the CPU controller 7;

[0015] Specifically, when there is a leakage current in the load circuit, the CPU controller 7 reads the output current value of the current transformer 6, and judges whether the leakage current value is greater than 30mA. If it is greater than 30mA, the CPU controller 7 sends a current to the release 5. , voltage signal, the household leakage protector trips normally, and plays the role of leakage protection. If it is less than 30mA, th...

Abstract

The invention provides a household electricity leakage protector with leakage current closing. The electricity leakage protector includes an upper cover and a pedestal and is characterized in that theupper cover includes a trial jump key, a reset key, an operation handle and a communication interface; the pedestal includes a CPU controller, a release and a current transformer; the trial jump key,the current transformer, the release and the communication interface are electrically connected to the CPU controller; the CPU controller is provided with a communication module; after the tripping of leakage current exists in a load circuit, manual closing can be performed on the electricity leakage protector, the CPU controller controls the release not to move, so that the electricity leakage protector can be powered on to work with the leakage current; and the CPU controller performs data transmission on the electricity leakage state and the leakage current of the electricity leakage protector. Through the control of the CPU controller, the electricity leakage protector can be powered on to work with the leakage current, so that the using flexibility of the electricity leakage protector can be greatly enhanced, and the using range of the electricity leakage protector can be enlarged.

Description

technical field [0001] The invention belongs to the field of household leakage protectors, in particular to a household leakage protector capable of switching on with leakage current. Background technique [0002] At present, electricity leakage often occurs in many household lines, but it is difficult for users to find out the location of the leakage in a short time, so it is impossible to provide emergency power supply without affecting the safety of use. This is also an important reason why many users do not install leakage protectors, but choose ordinary miniature circuit breakers. For example, some electrical equipment itself has a leakage current greater than 30mA, such as groundwater pumps, which must be replaced with ordinary miniature circuit breakers because they cannot supply power normally. As a result, the range of use of leakage protectors is restricted. [0003] Therefore, there is a need for a household leakage protector capable of both leakage protection an...
