Abstract

The invention relates to a plastic enclosure leakage circuit breaker with a multifunctional housing, comprising a quadrupole plastic enclosure circuit breaker, a leakage module fixedly connected on the circuit breaker, a zero sequence current transformer with a connecting plug fixedly connected on a base of the leakage module, a conductor penetrating through the zero sequence current transformer and a transformer with a connecting plug, an electron plate with a contact pin, an electron plate with a socket and a housing with a leakage module. The housing with the leakage module is provided with two circular holes fixed on the zero sequence current transformer, two inserts for fixing the electron plate with a wire connecting terminal thereon, a rectangular hole for plugging and fixing the electron plate with the contact pin and the electron plate with the socket as well as a hook plate for routing. By adopting the multifunctional housing, the number of parts of the leakage module of the circuit breaker is reduced, the volume of the plastic enclosure leakage circuit breaker is reduced, the cost is lowered, and the performance of the product is improved.

Description

The plastic enclosure leakage circuit breaker that has multifunctional housing

Technical field

The invention belongs to a kind of plastic enclosure leakage circuit breaker, particularly relate to a kind of plastic enclosure leakage circuit breaker that has multifunctional housing.

Background technology

The case overwhelming majority in the present known plastic casing formula residual current circuit breaker only possesses the function of cover, fast development along with China's low-voltage distribution electrical equipment cause, the volume of plastic enclosure leakage circuit breaker is more and more littler, function is more and more, performance is more and more reliable, to realize these functions in this limited space, volume-diminished, the function of part will be increased in the design.The function that therefore not only will possess case to the case objective requirement also will increase other function.

Summary of the invention

The present invention provides a kind of function that not only possesses case also to have the plastic enclosure leakage circuit breaker that has multifunctional housing of other functions for solving the technical problem that exists in the known technology.

The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:

It includes four utmost point mold cased circuit breakers, be connected in the electric leakage module on described four utmost point mold cased circuit breakers, be connected in the zero sequence current mutual inductor that has connection plug on the described electric leakage modular substrate, pass the conductor of zero sequence current mutual inductor, have the transformer of connection plug and also have an electron plate that has contact pin, one has the electron plate of socket and the case of an electric leakage module, and the case of described electric leakage module has two circular holes that are used for fixing on described zero sequence current mutual inductor, two are used for the inserts of the described electron plate that has a binding post on it, one is used for the hook plate of cabling with the described electron plate of contact pin and the oblong aperture and that the described electron plate that has socket plugs the usefulness that is fixed together of having.

Advantage and good effect that the present invention has are: owing to adopted multifunctional housing, thus reduced the quantity of circuit breaker electric leakage module part, dwindled the volume of plastic enclosure leakage circuit breaker, reduced cost, improved the performance of product.

Embodiment

For further understanding content of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

As shown in Figure 1, 2, 3, four utmost point mold cased circuit breakers 1 of plastic enclosure leakage circuit breaker are fixedlyed connected with the conductor 6 that passes instrument transformer by screw 5 with the pedestal 4 of electric leakage module.

Shown in Fig. 3,4,5,6, wherein Fig. 4 is the figure of modular substrate 4 shells of not leaking electricity among Fig. 1.Zero sequence current mutual inductor 7 and transformer 8 are fixed on the pedestal 4; The case 3 of electric leakage module is connected by two circular holes 14 and zero sequence current mutual inductor 7; The lead-out wire 11 of zero sequence current mutual inductor 7 and transformer 8 hangs on the hook plate 16 of case 3, and hook plate 16 plays the effect of trough, avoids lead-out wire to be pressed down; Case 3 also is connected by two inserts 15 and the electron plate 9 that has contact pin; Thereby in the binding post of the 12 insertion electron plates 9 of the connection plug on zero sequence current mutual inductor 7 and the transformer 8 power supply signal and detection signal are passed to electron plate 9; The contact pin plug of electron plate 9 inserts in the socket 10 of the electron plate 2 that has binding post through the oblong aperture 13 of case 3, from and power supply signal and detection signal passed to main circuit, make plastic enclosure leakage circuit breaker work.
