Description
Technical field
The utility model relates to a kind of manual override mechanism of earthed switch.
Background technology
The earthed switch electric and hand preferential shop (as shown in Figure 1) of prior art is all arranged on horizontal baffle 100, the secondary line of travel switch receives low-pressure cabinet from horizontal baffle, in actual motion, horizontal baffle sometimes needs situation about using of releasing, at this moment first the secondary line on travel switch must be removed, add time cost and add workload to staff.Secondly, also have the situation of colliding with in horizontal baffle disassembly process and occur, easily cause the damage of travel switch, this just turn increases Financial cost.Moreover, when operating personnel's manual operation earthed switch, earthed switch shield 101 first must open and make it push up to be pressed onto push rod 102 and push rod is down moved by existing earthed switch electric and hand preferential shop, push rod 102 top is pressed onto travel switch 103, travel switch 103 is cut off the electricity supply, after opening earthed switch shield, depress earthed switch interlocking slide plate again to allow earthed switch operating grip update hole, finally just can be grounded the electric and hand priority service of switch; Such operating procedure is too loaded down with trivial details, and need " turn over, press, insert " synchronously to carry out just can being grounded the manual operation of switch, such operating personnel operate and quite bother, and there will be in a rush situation.
Utility model content
The utility model provides a kind of manual override mechanism of earthed switch, and the earthed switch electric and hand preferential shop which overcoming the prior art described in background technology uses the shortcoming of time-consuming cost, Financial cost and use inconvenience.
The technical scheme adopted that the utility model solves its technical problem is:
A manual override mechanism for earthed switch, the manual operation cooperation of earthed switch is provided with handle hole and operating grip; This manual override mechanism comprises travel switch and stroke laminate, and the activity of the trip laminate is installed in this handle hole place and is positioned on the trip switch, the switchboard of the trip laminate contact the trip switch; During manual operation earthed switch, the operating grip that this correspondence stretches into handle hole can push up pressure the trip laminate, and the trip laminate and then top are pressed the switchboard of the trip switch and cut off the electric operating power supply of this earthed switch.
Among one embodiment: the trip switch is fixedly attached on switch cabinet body.
Among one embodiment: the trip laminate comprises a briquetting and a pad, this briquetting contact connects this pad, and this pad contact connects the switchboard of travel switch.
Among one embodiment: the trip laminate is installed on the dividing plate in this switch cubicle.
The technical program is compared with background technology, and its tool has the following advantages:
1, this manual override mechanism comprises travel switch and stroke laminate, and the trip laminate is installed in this handle hole place and is positioned on the trip switch; During manual operation earthed switch, the operating grip that this correspondence stretches into handle hole can push up pressure the trip laminate, and the trip laminate and then top are pressed the switchboard of the trip switch and cut off the electric operating power supply of this earthed switch; When carrying out the manual operation of earthed switch, the cut-out of electric control operation power supply can be realized after operating grip stretches into handle hole, without the need to touching travel switch make electric operating dump by opening shield, simplify the manually operated operating procedure of earthed switch, easy to operate and structure is simple.
2, the trip switch is installed on switch cabinet body, the secondary line of travel switch is without the need to through horizontal baffle, horizontal baffle needs to extract out when using without the need to the step through dismounting travel switch secondary line, save the operating time of operating personnel, travel switch also can not be damaged in the disassembly process of horizontal baffle simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 depicts the partial enlarged view of the earthed switch electric and hand preferential shop described in background technology.
Fig. 2 depicts the view of the manual override mechanism of a kind of earthed switch described in the utility model.
Embodiment
Embodiment one:
A manual override mechanism for earthed switch, the manual operation cooperation of earthed switch is provided with handle hole 10 and operating grip 20; This manual override mechanism comprises travel switch 1 and stroke laminate (not shown), and the activity of the trip laminate is installed in this handle hole 10 place and is positioned on the trip switch 1, the switchboard 11 of the trip laminate contact the trip switch 1; The trip switch is fixedly attached on switch cabinet body 30, and the trip laminate is installed on the dividing plate 40 in this switch cubicle.During manual operation earthed switch, operating grip 20 is aimed at and stretches into handle hole 10, in the process that operating grip 20 stretches into, the operating grip 20 that this correspondence stretches into handle hole 10 can push up pressure the trip laminate and down move, and the switchboard 11 of the trip laminate and then top pressure the trip switch 1 down moves and cuts off the electric operating power supply of this earthed switch.After operating grip exits handle hole, the natural resiliency restoring force due to the switchboard 11 of travel switch 1 flicks the trip laminate makes stroke laminate be returned to initial conditions, and travel switch 1 recloses electric operating power supply.
Embodiment two, please refer to Fig. 2:
The trip laminate comprises briquetting 2 and a pad 3, this briquetting 2 to be fixed on dividing plate 40 by a fixed block 4 and this briquetting 2 is rotatably connected on this fixed block 4, the pin-and-hole attaching of this pad 3 by a contiguous block 5 is offered, and one end contact of this pad 3 connects briquetting 2, other end contact connects the switchboard 11 of the trip switch 1, and this contiguous block 5 is fixed on this fixed block 4.During manual operation earthed switch, operating grip 20 is aimed at and stretches into handle hole 10, in the process that operating grip 20 stretches into, the operating grip 20 that this correspondence stretches into handle hole 10 can push up this briquetting 2 of pressure, this briquetting 2 rotates and pushes up pressure pad 3 and down moves, and pad 3 down moves and pushes up and presses the switchboard 11 of travel switch 1 down move and cut off the electric operating power supply of this earthed switch.After operating grip 20 exits handle hole, the natural resiliency restoring force due to the switchboard 11 of travel switch flicks pad 3 makes pad 3 and briquetting 2 be returned to initial conditions, and travel switch 1 recloses electric operating power supply.
As long as the manual override mechanism of embodiment one and a kind of earthed switch described in embodiment two can reach the effect cutting off electric operating power supply along band after operating grip being stretched into handle hole when manual operation earthed switch, electric operating dump is made to touch travel switch without the need to opening shield in prior art, simplify the manually operated operating procedure of earthed switch, operate more convenient, secondly because the trip switch has been retrofitted on switch cabinet body, when drawing horizontal baffle and using without the need to dismantling the secondary line of travel switch, and the damage avoided to travel switch in horizontal baffle disassembly process.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
