Abstract
The utility model relates to a protection switch which comprises a shell and a mutual inductor, wherein the mutual inductor comprises an intermediate mutual inductor and two side mutual inductors positioned on two sides of the intermediate mutual inductor; the axes of the two side mutual inductors are perpendicular to the axis of the intermediate mutual inductor; a stop block for blocking the axes is arranged between the two side mutual inductors; and the intermediate mutual inductor and the side mutual inductors are all hollow mutual inductors. The protection switch has the benefits that the mutual inductors are hollow mutual inductors, the axes of the adjacent mutual inductors are perpendicular to each other, the hollow mutual inductors have good linearity, and the mutual interference between the adjacent hollow mutual inductors is minimized.
Description
Technical field
The utility model relates to a kind of switch, especially a kind of control and protection switch.
Background technology
Control and protection switch electrical equipment, english abbreviation is CPS.Be the best substitute products of low-voltage electrical apparatuses such as circuit breaker, contactor, thermal relay, fuse.
Control is adopted modular single product structural shape with the protection switch product; The major function of integrated traditional circuit breaker (fuse), contactor, overload (or overcurrent, the phase failure) protection relay, starter, isolator etc.; Have far distance automatic controlling and direct on the spot manpower controlled function; Have panel indication and dynamoelectric signal warning function; Have the over-and under-voltage defencive function, have phase failure open-phase protection function, have cooperation time-current protection characteristic (having inverse time lag, specified time and instantaneous three section protection characteristic).Match functional module or annex as required, can realize control and protection all kinds of motor loads, distribution load.From its 26S Proteasome Structure and Function, no longer be single product such as contactor or circuit breaker or thermal relay etc., but a cover control protection system.Its appearance has fundamentally solved Traditional use discrete component (normally circuit breaker or fuse+contactor+overload relay) owing to selecting unreasonable control that causes and protection to cooperate irrational variety of problems; Particularly overcome when combining between the electric equipment products owing to the different appraisal standards of employing; Protective feature cooperates inharmonic phenomenon with control characteristic, greatly improved the operational reliability and continuous runnability of control and protection system.
Existing control and protection switch comprise the instrument transformer of housing, a plurality of annulars around its axle center, and said instrument transformer is the iron core instrument transformer; Through its acquired signal, linear poor, also the someone adopts hollow mutual inductor; But the hollow mutual inductor anti-interference is poor, again phase mutual interference easily.
The utility model content
The problem that the utility model will solve is to improve the problem that the instrument transformer of protection switch interferes with each other easily in the background technology.
In order to overcome the above problems; The utility model provides a kind of protection switch; Comprise housing, instrument transformer, said instrument transformer comprise instrument transformer in the middle of and two be positioned in the middle of the side instrument transformers on instrument transformer both sides, the axle center of said two side instrument transformers is all perpendicular to the axle center of middle instrument transformer; Be provided with the block that intercepts them between said two side instrument transformers, said middle instrument transformer and side instrument transformer are hollow mutual inductor.
The both sides of instrument transformer in the middle of said side instrument transformer is symmetrically set in.
Said block and instrument transformer clamping matching.
Instrument transformer is located at outside the housing in the middle of said, and the side instrument transformer is located in the housing.
Said a plurality of instrument transformer is setting.
Also be provided with removable cover on the said housing, said removable cover is provided with the block with its one.
The described protection switch of the utility model, said instrument transformer are hollow mutual inductor, and the axle center of two adjacent instrument transformers is vertical each other, the hollow mutual inductor good linearity, and make that mutual interference is minimized between the adjacent hollow mutual inductor.

Marginal data: 1, housing; 2, removable cover; 3, middle instrument transformer; 4, side instrument transformer; 5, block.
Embodiment
Below in conjunction with accompanying drawing a kind of protection switch of the utility model is described further.
Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, a and b are respectively the structural representations of protection switch among Fig. 1, among Fig. 1 a enclosing cover are arranged, and do not have enclosing cover among Fig. 1 b.Fig. 2 a, b, c are respectively the sketch mapes of the instrument transformer different angles of putting, and Fig. 4 a, b are respectively the sketch map of the different angles that the instrument transformer another kind puts.The protection switch of present embodiment; Comprise housing 1, instrument transformer; Instrument transformer 3 and two side instrument transformers 4 that are positioned at middle instrument transformer 3 both sides in the middle of said instrument transformer comprises one; The axle center of two side instrument transformers 4 all perpendicular to the axle center of middle instrument transformer 3, is provided with the block 5 that intercepts them between two side instrument transformers 4, and middle instrument transformer 3 and side instrument transformer 4 are hollow mutual inductor.The axle center of said two side instrument transformers 4 is all perpendicular to the axle center of middle instrument transformer 3; Vertically comprising described in the utility model intersected or non-intersect two kinds of situation; Such as the axle center of the axle center of side instrument transformer 4 and middle instrument transformer 3 respectively on different plane; Though can't intersect, they still can be orthogonal, also belongs to the protection range of the utility model.The described protection switch of the utility model, said instrument transformer are hollow mutual inductor, the hollow mutual inductor good linearity, and make that mutual interference is minimized between the adjacent hollow mutual inductor.
In the present embodiment, the both sides of instrument transformer in the middle of side instrument transformer 4 is symmetrically set in.In the present embodiment, said block 5 and instrument transformer clamping matching.Position through 5 pairs of instrument transformers of block, what make that instrument transformer can be stable remains on the position that it needs.The protection switch of present embodiment, said middle instrument transformer 3 is located at outside the housing 1, and side instrument transformer 4 is located in the housing 1.Can certainly be transformed to all and be located in the housing.Said instrument transformer is setting.This is a kind of execution mode of present embodiment, can make a lot of conversion.In the present embodiment, said a plurality of instrument transformers 3 are setting.Can certainly conversion, as shown in Figure 4, middle instrument transformer is a horizontal positioned.In addition, also be provided with removable cover 2 on the said housing 1, removable cover 2 is provided with the block 5 with its one.Convenient when making installation through being provided with removable cover 2.
The utility model is not limited to above embodiment and conversion.
