Abstract
On the basis of available breaker, the casing is extended lengthwise to form a space for installing one leakage trip driver. The driver consists of one zero sequence mutual inductor, one circuit board and one electromagnetic contactor, the output of the zero sequence mutual inductor is connected to the circuit board, the output signal current of the circuit board is led to the winding of the electromagnetic contactor and the drawing bar fixed onto the core rod of the electromagnetic contactor contacts with the trip arm of the trip driver. The said breaker has the same width, 19mm as available one and increased leakage protection function.
Description
The present invention relates to a kind of width and be 18 millimeters two-wire circuit breaker.
Width is that 18 millimeters two-wire circuit breaker has the housing that is assembled by three housing parts in left, center, right; housing is provided with handle, release, short circuit dropout driver, overlond trip driver, moving contact, fixed contact, binding post and extinguisher; obviously; this circuit breaker has short circuit and overload protection function; but be provided with creepage protection function, its defencive function is incomplete.In order to address this problem; present scheme is that to set up a width in a side of two-wire circuit breaker also be 18 millimeters earth leakage protective device; product width promptly reaches 36 millimeters; volume has increased more than one times; obviously; such product not only profile is too fat to move, and consumptive material is many, and influences the possibility that other electric equipment products are installed as usual.
The purpose of this invention is to provide a kind of width that has electric leakage, short circuit and overload protection function concurrently and be 18 millimeters two-wire circuit breaker.
Solution of the present invention is that the one-sided along its length extension of a side that the overlond trip driver is installed in the housing forms for the space that electric leakage dropout driver is installed, this electric leakage dropout driver is by zero-sequence transformer, electron plate and electromagnetic attracting device are formed, wherein the signal input line of zero-sequence transformer is to connect the two piece leads of moving contact with binding post, the output line of zero-sequence transformer inserts electron plate, handle the solenoid of the signal code conducting electromagnetic attracting device of output through electron plate, the pull bar that is fixed on the plug of electromagnetic attracting device then contacts with the trip arm in the release.
Essence of the present invention is under the prerequisite that keeps 18 millimeters of width; in housing, form one for the space that electric leakage dropout driver is installed; this electric leakage dropout driver provides electric leakage signal by zero-sequence transformer; making electromagnetic attracting device get electric driving plug after electron plate is handled moves and spurs the trip arm release is threaded off; at this moment; moving contact promptly disengages with fixed contact; therefore, the present invention has increased creepage protection function again on 18 millimeters the basis of two-wire circuit breaker.In addition, shell length of the present invention only must increase by 15 millimeters, can hold electric leakage dropout driver; that is to say increases a creepage protection function, and the cost of product increases few, is very economical; simultaneously, this technical solution does not hinder installing as usual of other electric equipment products.
Illustrate particular content of the present invention below in conjunction with drawings and Examples.
Fig. 1: structure chart of the present invention;
The vertical view of Fig. 2: Fig. 1;
Fig. 3: electric leakage prompting structure chart partly;
Fig. 4: earth leakage protective circuit theory diagrams.
As shown in the figure, width is that 18 millimeters two-wire circuit breaker has housing 1 and is arranged on handle 2 in the housing 1, release, short circuit dropout driver, overlond trip driver 5, moving contact 6,7, fixed contact 8,9, binding post 10,11,12,13 and extinguisher 14,15, the one-sided along its length extension of a side that overlond trip driver 5 is installed in the housing 1 of the present utility model forms for the space 16 that electric leakage dropout driver is installed, this electric leakage dropout driver is by zero-sequence transformer 17, electron plate 18 and electromagnetic attracting device are formed, wherein the signal input line of zero-sequence transformer 17 is to connect moving contact 6,7 with binding post 12, two leads 19 of 13,20, the output line of zero-sequence transformer 17 inserts electron plate 18, handle the solenoid 21 of the signal code conducting electromagnetic attracting device of output through electron plate 18, be fixed on 23 on pull bar on the plug 22 of electromagnetic attracting device with 24 contacts of the trip arm in the release.Described release, short circuit dropout driver and overlond trip driver 5 are known technology, and wherein release is by swing arm 25, tripping arm 26, the trip arm 24, contact arm 27,28, some springs be connected handle 2 and form with the members such as connecting rod 29 of swing arm 25; Short circuit dropout driver is made up of solenoid 3, plug 4 and spring, and overlond trip driver 5 is exactly the thrermostatic bimetal-plate of single-ended supporting.According to routine, also be provided with the leak(age) test circuit of forming by resistance R and test button 30 in the housing 1, wherein test button 30 stretches out in housing 1.For the tripping operation of pointing out circuit breaker causes under the electric leakage situation, can the pivoted arm 32 that be supported on fulcrum 31 be set in the inboard of overlond trip driver 5, the one end is with plug 22 contacts, the other end indicates the prompting look, and be provided with the match hasp 34 of the corner that limits pivoted arm 32 of the hasp on the handle 2 33, pivoted arm back-moving spring 35 is sleeved on the fulcrum 31, and the prompting look then is shown in the display window 36 on the housing 1.Present embodiment is designed to fulcrum 31 with the concentric cantilever minor axis structure of the bolster 37 of the trip arm 24, can make structure compact more like this.Housing 1 is a combining structure, and is assembled by three of left, center, right.For width is that 18 millimeters two-wire circuit breaker all adopts the card rail to install, and the present invention and is arranged on buckle 38 lower right of housing 1 too.
