Description

A kind of Minitype electrical leakage breaker

Technical field

It the utility model is related to earth leakage protective and electric leakage component technical field, more particularly to a kind of small-sized leakage, breaking Device.

Background technology

Leakage current exceedes predetermined value in RCCB (residual current circuit-breaker) circuit When can auto-action switch.Conventional RCCB is divided into voltage-type and the class of current mode two, and current mode is divided into electromagnetism Two kinds of type and electron type.RCCB is used to prevent personal electric shock, should be got an electric shock according to two kinds of directly contact and mediate contact anti- The different of shield are required to select.Voltage-type RCCB is used for the earth-free low voltage electric network of transformer neutral point.It is characterized in When the person gets an electric shock, there is a higher voltage over the ground in zero line, causes the actuating of relay, power switch tripping operation.

Current mode RCCB is mainly used in the low-voltage distribution system of transformer neutral point ground connection.It is characterized in when the person During electric shock, a leakage current is detected by zero sequence current mutual inductor, makes the actuating of relay, power switch disconnects.1) directly connect The protection got an electric shock, because the harm that directly contact is got an electric shock is bigger, caused consequence is serious, so to select in higher sensitivity RCCB, should installation action electric current be in the loop 30mA to electric tool, mobile electrical devices and temporary line, RCCB of the actuation time within 0.1s.The residential building more to household electrical appliance, is preferably mounted on house lead in electric energy meter Afterwards.2) mediate contact prevention of electric shock, the mediate contact of different places are got an electric shock, and can cause different degrees of injury to the person, so, Different places should install different RCCBs.The place larger to the harmfulness easily got an electric shock, it is desirable to remolding sensitivity compared with High RCCB.In moist place than drying the dangerous much greater of place electric shock, installation action electric current is typically answered For 15-30mA, RCCB of the actuation time within 0.1s.

But lack one kind in the prior art and carried out by testing button under the environment such as circuit failure or experiment The breaker of turn-off module, therefore it provides it is technical problem urgently to be resolved hurrily that can cross the breaker for test open circuit.

Utility model content

The purpose of the utility model embodiment is to provide a kind of Minitype electrical leakage breaker, gone out by testing button in circuit Under the existing environment such as failure or experiment, the function of RCCB is verified again, it is possible to increase the safety of integrated circuit Property.

To reach above-mentioned purpose, the utility model embodiment discloses a kind of Minitype electrical leakage breaker, including breaker sheet Body, in addition to：Test button, electromagnet coil；The experiment button is arranged in the case surface of the breaker body, and The either above or below of the experiment button is provided with corresponding status indicator lamp, the experiment button and amplifying circuit phase Even, the amplifying circuit is connected with controlling switch.

Using the utility model embodiment, play a part of simulation electric leakage by testing button, test button and electromagnet Coil is connected with controlling switch, and i.e. circuit turn-on circuit is in leakage condition after experiment button press is gone down, if now Controlling switch disconnects, then shows that breaker is in normal state, otherwise in abnormality.Using provided by the utility model Embodiment, by testing button under the environment such as circuit failure or experiment, the function of RCCB is carried out again Checking, it is possible to increase the security of integrated circuit.

Certainly, implementing any product of the present utility model or method must be not necessarily required to reach all the above simultaneously Advantage.
