Abstract
The utility model relates to a molded case switch with an electric switch-on and switch-off function. A switch-on button QA and a normally-closed contact of an intermediate relay SJ1 are connected in series with a coil of a switch-on relay SJ2, and then, the switch-on button QA, the normally-closed contact of the intermediate relay SJ1 and the coil of the switch-on relay SJ2 are connected in parallel between a wire entering-side phase line A and a neutral line N; a switch-on motor M is connected in series with a second normally-open contact of a switch-on relay SJ3, and then, the switch-on motor M and the second normally-open contact of the switch-on relay SJ3 are connected in parallel between the wire entering-side phase line A and the neutral line N; a coil of the intermediate relay SJ1 is connected in parallel between a wire outgoing-side phase line a and the neutral line N; a normally-open contact of a switch-off relay SJ3 is connected in series with a tripping coil T, and then, the normally-open contact of the switch-off relay SJ3 and the tripping coil T are connected in parallel with the coil of the intermediate relay SJ1; and a switch-off button TA is connected in series with a coil of the switch-off relay SJ3, and then, the switch-off button TA and the coil of the switch-off relay SJ3 are connected in parallel with the coil of the intermediate relay SJ1. Through setting a control circuit, the switch-on motor M drives an electric operating mechanism to perform switching on, and the switch-off relay SJ3 sends out control signals to the tripping coil T, such that switching off can be realized. The molded case switch with the electric switch-on and switch-off function is advantageous in simple control circuit, time-saving and labor-saving properties in application, reliable operation, reduction of human factor-cased contact adhesion time, and greatly prolonged service life.
Description
Technical field
The utility model relates to a kind ofly moulds shell switch with electronic divide-shut brake.
Background technology
Mould shell switch, refer to that all parts are all sealed in plastic casing, comprise Pyromagnetic release, main contact, arc control device and operating mechanism etc.The most shell switch of moulding generally adopts manual operation, and along with cut-offfing the increase of capacity, hand operation is moulded the divide-shut brake handle of shell switch, wastes time and energy; In addition, because dependent manual operation handle is firmly inhomogeneous, if manual operations can not make the smooth separating brake of main contact, the arc time when additionally increasing main contact disjunction.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, provides a kind of time saving and energy saving, reliable operation mould shell switch with electronic divide-shut brake.
For achieving the above object, the utility model adopts a kind ofly like this moulds shell switch with electronic divide-shut brake, comprise manual-operating mechanism and motor-operating mechanism, described motor-operating mechanism comprises combined floodgate motor M, closing relay SJ2, separating brake relay SJ3 and auxiliary relay SJ1, switch knob QA, after the coil series connection of the normally closed interlock of described auxiliary relay SJ1 and described closing relay SJ2, be connected between inlet wire side phase line A and neutral line N, the first normally open contact of described closing relay SJ2 and described switch knob QA also connect, between inlet wire side phase line A described in described combined floodgate motor M is connected to after connecting with the second normally open contact of described closing relay SJ3 and described neutral line N, the coil of described auxiliary relay SJ1 is connected between outgoing line side phase line a and neutral line N, the normally open contact of described separating brake relay SJ3 is connected with tripping coil T afterwards and the coils from parallel connection of coils of described auxiliary relay SJ1, after opening button TA connects with the coil of described separating brake relay SJ3 with the coils from parallel connection of coils of described auxiliary relay SJ1.Compared with the prior art, the beneficial effects of the utility model are embodied in: by the setting of control circuit, closed a floodgate by combined floodgate motor M driving electric operating mechanism, send control signal by separating brake relay SJ3 and realize separating brake to release T, control circuit is simple, and it is time saving and energy saving to use, and reliable operation, reduce the contact adhesion time that human factor causes, improved widely life of product.
The described shell switch of moulding with electronic divide-shut brake also comprises Long-distance Control switch knob S1 and Long-distance Control opening button S2, described Long-distance Control switch knob S1 is in parallel with described switch knob QA, and described Long-distance Control opening button S2 is in parallel with described opening button TA.By the setting of Long-distance Control switch knob S1 and length of run control opening button S2, can realize the divide-shut brake remote signalling operation in short-range.

Embodiment
As shown in Figure 1, a kind ofly mould shell switch with electronic divide-shut brake, comprise manual-operating mechanism and motor-operating mechanism, motor-operating mechanism comprises combined floodgate motor M, closing relay SJ2, separating brake relay SJ3 and auxiliary relay SJ1, switch knob QA, after the coil series connection of the normally closed interlock of auxiliary relay SJ1 and closing relay SJ2, be connected between inlet wire side phase line A and neutral line N, the first normally open contact of closing relay SJ2 and switch knob QA also connect, combined floodgate motor M is connected between inlet wire side phase line A and neutral line N after connecting with the second normally open contact of closing relay SJ3, the coil of auxiliary relay SJ1 is connected between outgoing line side phase line a and neutral line N, the normally open contact of separating brake relay SJ3 is connected with tripping coil T afterwards and the coils from parallel connection of coils of auxiliary relay SJ1, opening button TA connects with the coil of separating brake relay SJ3 afterwards and the coils from parallel connection of coils of auxiliary relay SJ1.
The shell switch of moulding with electronic divide-shut brake also comprises Long-distance Control switch knob S1 and Long-distance Control opening button S2, and Long-distance Control switch knob S1 is in parallel with switch knob QA, and Long-distance Control opening button S2 is in parallel with opening button TA.
In the time of " separating brake " state, outgoing line side a, N no power, press switch knob QA, and the coil of closing relay SJ2 obtains electric, and combined floodgate motor M brings into operation, and driving electric operating mechanism closes a floodgate; Once, outgoing line side a, N energising, the coil of auxiliary relay SJ1 obtains electric, meanwhile, and the coil losing electricity of closing relay SJ2, thereupon, the second normally open contact of closing relay SJ2 sends the control signal of " shutdown ", and combined floodgate motor M is out of service.
