Abstract
The utility model relates to a release device for leakage protection plugs, which comprises a spring and an iron core mounted on a bracket and leakage coil wound on the bracket, wherein an insulation bushing is provided out of the leakage coil, and a short circuit coil is wound around the insulation bushing. The utility model can solve the weaknesses with prior art that release devices for leakage protection plugs release only for leakage signals, with a quite limited scope of application. With help of the above design, the release device for leakage protection plugs can release both for leakage signals and short circuit signals simply by providing a set of bracket, a spring and an iron core, without increasing the overall size of the plugs while maintaining the same functions. The utility model has the advantages of: simple and compact structure, strong reliability and convenient use.
Description
Affiliated technical field
The utility model relates to a kind of leakage protecting plug trip gear.
Background technology
Traditional leakage protecting plug trip gear all comprises spring, the iron core that is assemblied in the support and is wrapped in electric leakage coil on the support; only under the situation that produces electric leakage signal; iron core just can move dropout; therefore limitation is very strong; if subsidiary short-circuit protection function; toward firmly all will in plug, establishing cover support, spring and an iron core in addition, cause the volume of plug big, cost is high.
Summary of the invention
The leakage protecting plug trip gear only produces the problem that dropout is moved, limitation is strong, the scope of application is wideless to electric leakage signal in the prior art in order to overcome.The utility model provides a kind of leakage protecting plug trip gear, and this leakage protecting plug trip gear not only has the earth leakage protective effect, has short-circuit protection function simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is: comprise spring, the iron core that is assemblied in the support and be wrapped in electric leakage coil on the support at electric leakage coil peripheral hardware separation sleeve is arranged, twine short-circuited coil on the separation sleeve.
The utility model is by above-mentioned design; under the situation of having only cover support, spring and an iron core, make the leakage protecting plug trip gear all produce the action of threading off at electric leakage signal and short-circuit signal; and under the prerequisite of identical function, do not increase the overall volume of plug, have simple and compact for structure, good reliability, advantage easy to use.
Description of drawings
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model;
Embodiment
As shown in the figure, the utility model comprises spring 2, the iron core 3 that is assemblied in the support 1 and is wrapped in electric leakage coil 4 on the support 1, be provided with separation sleeve 5 outside electric leakage coil 4, separation sleeve 5 is drum shape and is sleeved on outside the electric leakage coil 4, twines short-circuited coil 6 on the separation sleeve 5 again.When occurring short circuit or overcurrent on the protected circuit, then short-circuited coil 6 produces high-intensity magnetic field, and pulling iron core 3 produces the action of threading off, and plays the short-circuit protection effect.
Claims (1)
