Abstract
The utility model relates to a width 18 modularized clamping-rail type dual-line breaker. On the basis of the public-known technology, a zero-sequence mutual inductor, an electron plate and an electromagnetic attracting device are arranged at the utility model; a core rod of the electromagnetic attracting device is contacted with the other end of a tripping arm of a tripper, and two conductor wires which are used for connecting with a wiring terminal and a moving contact are used as a signal input line of the zero-sequence mutual inductor; a signal output line of the zero-sequence mutual inductor is connected with the electron plate, and the signal current which is amplified by the electron plate is conducted to an electromagnetic coil of the electromagnetic attracting device; thereby, when the zero-sequence mutual inductor provides an electrical-leakage signal, the core rod can drive the tripper to cause the moving contact and a static contact to be disengaged from each other; thereby, the utility model has the function of electrical-leakage protection.
Description
The utility model relates to a kind of width 18 modularization clamping-rail two-wire circuit breakers.
The purpose of this utility model provides a kind of width 18 modularization clamping-rail two-wire circuit breakers with creepage protection function.
Solution of the present utility model is that zero-sequence transformer, electron plate and electromagnetic attracting device are set in housing, and the plug of electromagnetic attracting device contacts with the other end of the trip arm of release, the connection binding post is the signal input line of zero-sequence transformer with two leads of moving contact, and the output line of zero-sequence transformer inserts electron plate, then imports the solenoid of electromagnetic attracting device through electron plate amplifying signal electric current.
The essence of above-mentioned technical solution be in the housing of width 18 modularization clamping-rail two-wire circuit breakers extrusion space be provided with one the cover provide electric leakage signal by zero-sequence transformer; after electron plate amplifies, import the solenoid of electromagnetic attracting device again and plug is moved; promoting the trip arm at last threads off also and then the earth leakage protective device that moving contact is disengaged with fixed contact release; therefore, the utility model just becomes the width 18 modularization clamping-rail two-wire circuit breakers with creepage protection function.
Illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Fig. 1: cut-away view of the present utility model;
Fig. 2: earth leakage protective circuit theory diagrams.
As shown in the figure, width 18 modularization clamping-rail two-wire circuit breakers have binding post 1,2,3,4, switch knob 5, release 6, thrermostatic bimetal-plate 7, moving contact 8,9 and fixed contact 10,11, and be installed in the housing 13 that is provided with draw-in groove 12, thrermostatic bimetal-plate 7 is with an end in contact of the trip arm 14 of release 6, moving contact 8,9 are arranged on the release 6, the utility model further is provided with zero-sequence transformer 15 in housing 13, electron plate 16 and electromagnetic attracting device, and the plug 17 of electromagnetic attracting device contacts with the other end of the trip arm 14, connect binding post 1,3 with moving contact 8,9 two leads 18, the 19th, the signal input line of zero-sequence transformer 15, and the output line 20 of zero-sequence transformer 15,21 insert electron plate 16, then import the solenoid 22 of electromagnetic attracting device through electron plate 16 amplifying signal electric currents.Release 6 herein is known technologies, by swing arm, the trip arm 14, spring be connected switch knob 5 and form with the members such as connecting rod of swing arm, in addition, the leak(age) test circuit of being made up of resistance R and test button 23 will be set generally according to routine.The described housing 13 general composite assembly structures that adopt, and form the cavity that can hold all members.
