Embodiment Construction

[0054] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0055] see Figure 1A As shown, it is a three-dimensional schematic diagram of the combination of the first embodiment of the leakage detection module of the present invention and the circuit breaker body; the combination of the leakage detection module 2 and the circuit breaker body 1 reflects a circuit breaker as a whole function. This combination can be fixedly connected together, but it is better to use the plug-and-play method, which can better reflect the versatility of modularization.

[0056] see Figure 1B and Figure 1C As shown, they are respectively a three-dimensional schematic view and a structural exploded three-dimensional schematic view before the leakage detection module embodiment 1 of the present invention is combined with the circuit breaker body; the leakage detection module 2 is co...

Abstract

The invention relates to a current leakage detection module and a current leakage protection circuit breaker with the current leakage detection module, wherein the current leakage protection circuit breaker with the current leakage detection module comprises the current leakage detection module and a circuit breaker body, wherein the current leakage detection module is used for detecting whether a current leakage fault exists in a circuit; the circuit breaker body is combined with the current leakage detection module and used for producing a circuit breaking action when the current leakage fault exists; and the current leakage detection module comprises a first connecting seat which is connected with a second connection realizing structure on the circuit breaker body for controlling the signal connection.

Description

technical field [0001] The invention relates to a leakage protection device, in particular to a modularized and standardized leakage detection module which can be combined with an existing circuit breaker body and a leakage protection circuit breaker with the leakage detection module. Background technique [0002] The circuit breaker is a very important electrical equipment with a wide range of applications. As people pay more and more attention to the safety of electricity use, there are more and more studies on the peripheral functions with the circuit breaker as the core. Among them, leakage protection is a A very important direction. The existing leakage protector is commonly known as leakage switch. It is used to prevent personal electric shock and electrical fire when the circuit or electrical insulation is damaged and short-circuited to the ground. It is generally installed in the socket of each household's distribution box. On the circuit and the power inlet line of ...
