Abstract
A protective limit plug-in unit of a spring lifting pin of a central switch is provided with a baffle. One side of the baffle is connected with an elastic clip. After the central switch and a switch cabinet are shifted out, the baffle is used for pressing the spring lifting pin at the position below the right side of the bottom of the central switch to retraction state. The elastic clip clamps the bottom of the central switch. Consequently, the spring lifting pin keeps in retraction state all the time so that the central switch can be smoothly moved. The protective limit plug-in unit is simple and reasonable in structure, reliable and convenient in use, and capable of not only facilitating movement of the central switch, but also enhancing the safety of movement.
Description
Technical field
The utility model relates to a kind of protection instrument, and specifically a kind of mid-switch spring ejector pin is protected spacing plug-in unit.
Background technology
Intermediate switchgear cabinet is made up of mid-switch and switch cubicle, and mid-switch places the middle part in the switch cubicle, and it extensively applies among the 10kV and 35kV power supply-distribution system of electric power system and industrial enterprise.When mid-pass need be overhauled, mid-switch must be shifted out in cabinet by dedicated platform earlier, and then mid-switch is separated with dedicated platform, moves on the dedicated platform after mid-switch maintenance is good again and delivers in the switch cubicle.Lower right, mid-switch bottom has a spring knock pin, at present, the process that mid-switch is unloaded from dedicated platform or mid-switch moved to from other places on the dedicated platform, need be by manually propping up spring knock pin all the time with hand, make it keep retracted state, to avoid slide rail on spring knock pin and the dedicated platform to bump and to cause damage, in moving mid-switching process, by manually propping up spring knock pin all the time, can give to move to operate and make troubles, and potential safety hazard is arranged with hand.
The utility model content
The purpose of this utility model is to provide a kind of mid-switch spring ejector pin to protect spacing plug-in unit, and this protects spacing plug-in unit can make the spring knock pin of mid-switch remain on retracted state, so that the moving of mid-switch.
For achieving the above object, the utility model adopts following scheme: mid-switch spring ejector pin is protected spacing plug-in unit, and it has a baffle plate, is connected with an elastic clip in the inboard of baffle plate.
By such scheme as seen, after mid-switch and switch cubicle shifted out, with baffle plate the bottom-right spring knock pin in mid-switch bottom is compressed to retracted state, and elastic clip is clipped on the bottom of mid-switch, can make spring knock pin remain retracted state, and then can move mid-switch smoothly.
The utility model is simple and reasonable for structure, and it is reliably convenient to use, and it can bring convenience to moving mid-switch, can improve the fail safe in moving again.
