Abstract

The invention relates to a push-stem circuit-breaker dual-purpose reclose device whose reclosing operation can be operated automatically or hand-operated, comprising an electrical control circuit and a motor operating element. The motor (1) is rooted on the shell and a tumbler disc (2) integrated with a catch bar (6) is fixed to an axle bearing (8). The tumbler disc (2) guides the catch bar (6) moving on the guide shaft. When the catch bar (6) reaches the position that the switch recluses, it contacts the overtravel-limit switch, and shuts down the motor (1) automatically. The crank on the front panel can move freely. When the electronic circuit is in abnormal state, push the hand-operating button on the front panel to reposition the motor.

Description

Manual and the automatic closing device of direct-push residual current circuit breaker

Technical field

This utility model relates to a kind of multiduty electric switch that uses with the low voltage electric network matched with devices, can electric switch-on, the device that can manually close a floodgate again in residual current circuit breaker.

Background technology

In existing numerous circuit at existing numerous circuit breaker, mechanical structure, what have has only electric leakage, and can not close a floodgate after the electric leakage; Though what overlapping of having but can not be manual, most residual current circuit breaker were automatically, the dual-use manual closing device adopts is the turbine type operating mechanism.

Summary of the invention

The technical scheme that the utility model adopted is: this device is to the technical deficiency of existing various electric leakage mechanical structures, design a kind of after the residual current circuit breaker tripping operation, electronic resetting and combined floodgate, the direct-push residual current circuit breaker dual-purpose apparatus of hand-reset and combined floodgate under abnormality under normal condition.

The beneficial effects of the utility model are that the handle that can directly pull on the panel at the breaker closing state carries out freely dividing, closing a floodgate.When electronic circuit is unusual, can pin the hand push button on the panel, put in place up to motor, handle be can freely pull and branch, combined floodgate carried out.But electronic closing by hand again.

Description of drawings

Accompanying drawing is the motor-operating mechanism schematic diagram

Among the figure: 1. motor; 2. rotary disk; 3. lead limit switch; 4. plate washer; 5. handle installing rack; 6. catch bar; 7. installing hole; 8. bearing; 9. guide shaft;

Embodiment

The shell of device is integrated, parts are welded on superincumbent the right, with motor (1) close-fitting in the above, rotary disk (2) is welded together with catch bar (6), again it is fastened on the bearing (8), the place of place's projection is arranged on the device bar of catch bar (6), cooperate with travel switch, after control motor (1) running puts in place, self-braking device.Motor (1) is fastening with screw, in two groups of symmetrical holes of guide shaft (9) device below housing, block with corresponding jump ring respectively at two, plate washer (4) is enclosed within the guide shaft (9), and under the promotion of catch bar (6), rotary disk (2) moves in a circle in the space of regulation, can be with plate back and forth promotion in prescribed stroke, operating grip is screwed on handle installing rack (5), and operating grip and circuit breaker handle connect together, and circuit breaker can be carried out divide-shut brake.When pulley was pushed to the position of switch combined floodgate, catch bar (6) touched travel switch, makes motor (1) out of service automatically, and at this moment, the handle on the panel can freely be pulled up and down.

Under normal circumstances, after the residual current circuit breaker tripping operation, electric control circuit instruction exchanges reversible electric machine (matching with the travel switch) combined floodgate that automatically resets, if switch itself is in "on" position, just can directly pull the handle on the panel when meeting plant failure or needing when manual, when if switch also is parked in other position, pin the closing by hand button on the panel earlier, when motor quit work, the handle that can pull on the panel closed a floodgate.

Claims

1, the manual and automatic closing device of a kind of direct-push residual current circuit breaker, it is characterized in that: it is made of electric control circuit and motor-operating mechanism two big departments, motor (1) close-fitting is in the shell upper right side, rotary disk (2) is an one with catch bar (6) limit, be fastened on the bearing (8), handle on the panel can freely be pulled up and down, and hand push button is housed on the panel, and above-mentioned parts are located with corresponding keeper securing member and be fastening.

2, the manual and automatic closing device of direct-push residual current circuit breaker according to claim 1 is characterized in that motor is installed in the upper right side of shell.

3, the manual and automatic closing device of direct-push residual current circuit breaker according to claim 1 is characterized in that adopting the direct-push operating mechanism.
