Description

Non-outage detection type leakage protector Technical Field The utility model belongs to the technical field of leakage protectors, and particularly relates to a non-outage detection type leakage protector. Background The leakage protector, called leakage switch for short, is mainly used for protecting the life of life with fatal danger when the equipment has leakage fault, has overload and short-circuit protection function, can be used for protecting the overload and short circuit of the circuit or motor, and can also be used for starting the circuit without frequent conversion under normal condition. The working principle of the leakage protector is to judge whether leakage exists or not by detecting whether the current of the live wire and the zero wire are balanced or not. If leakage occurs, the current imbalance triggers the protector to trip. However, prolonged periods of non-use may result in reduced sensitivity and failure to properly detect leakage. Therefore, in order to ensure that the leakage protector can work normally, the test button of the leakage protector needs to be pressed once every month so as to simulate the leakage condition and check whether the protector can work normally. However, the existing leakage protector must trigger a tripping action during testing, which causes circuit interruption, thus causing unplanned shutdown of the electric equipment, and frequent testing affects power supply continuity. In particular, in special occasions such as hospitals and data centers, conventional detection cannot be performed. Disclosure of utility model In order to solve the above problems, the present utility model provides a non-outage detection type earth leakage protector, which can perform a conventional test once a month without triggering an outage. The technical scheme of the utility model is that the non-outage detection type leakage protector comprises a breaker main body, a leakage protection module and a bottom plate, wherein the breaker main body is fixedly arranged on the bottom plate, a guide rail is arranged on the bottom plate, and the leakage protection module is slidably arranged on the guide rail; When the circuit breaker main body is combined with the leakage protection module, the test button is arranged under the baffle, and the leakage protection module can drive the circuit breaker main body to trip through a mechanical interlocking mechanism; The leakage protection module moves along the guide rail until the test button is exposed out of the baffle plate, and the mechanical interlocking mechanism is in a disconnection state. On the basis of the scheme and as a preferable scheme of the scheme, the side face of the guide rail is provided with a limiting block, when the leakage protection module is propped against the position of the limiting block, the test button is exposed outside, and the mechanical interlocking mechanism is in a disconnection state. On the basis of the scheme and as a preferable scheme of the scheme, the upper end and the lower end of the breaker main body are provided with clamping grooves, the upper end and the lower end of the leakage protection module are provided with clamping pieces, and the clamping pieces can be buckled on the clamping grooves when the breaker main body is spliced with the leakage protection module.
