Description
Technical field
The utility model relates to a kind of isolating switch interlock, the interlock particularly between a kind of high-voltage switch cabinet isolation switch hand-power operating mechanism.
Technical background
High-tension switch cabinet is the visual plant in power supply-distribution system, isolating switch is wherein important device for switching, realize closing a floodgate or separating brake by handling its hand-power operating mechanism, play and ensure High-Voltage Electrical Appliances and the safety of device when service work and the effect of isolation voltage, installation 2 or 3 isolating switches are needed in some special purpose schemes, but in the middle of maintenance uses, user side requires that these 2 or 3 isolating switches can not be in the state of separating brake simultaneously, an isolating switch at least will be had to be in "on" position, therefore in order to meet demand and the security consideration of user, a kind of interlocking of two hand-power operating mechanisms thus device that isolating switch is interlocked of allowing need be designed.
Utility model content
The purpose of this utility model is to provide a kind of use safety, interlocks reliable high-voltage switch cabinet isolation switch interlock, to overcome the deficiency that above-mentioned prior art exists.
The technical scheme that the utility model is taked is: a kind of high-voltage switch cabinet isolation switch interlock, the hand-power operating mechanism comprising isolating switch and the active pin be laterally arranged between two hand-power operating mechanisms; The pedestal waist of described hand-power operating mechanism has and the pin-and-hole of locating lockhole and being communicated with, described active pin is a bar shaped cuboid, in the pin-and-hole that a wherein hand-power operating mechanism is inserted in its one end and location lockhole, the pin-and-hole that the other end rides over another hand-power operating mechanism does not insert location lockhole.
Its further technical scheme is: the two ends, left and right of described active pin are respectively equipped with dog screw, described each end dog screw is greater than the distance of location lockhole to hand-power operating mechanism pedestal outer wall apart from the distance of corresponding active pin termination, when the left end of active pin inserts in the location lockhole of left side hand-power operating mechanism, the dog screw of left end just blocks the pedestal outer wall of left side hand-power operating mechanism, when the right-hand member of active pin inserts in the location lockhole of the right hand-power operating mechanism, the dog screw of right-hand member just blocks the pedestal outer wall of the right hand-power operating mechanism.
Owing to adopting technique scheme, a kind of high-voltage switch cabinet isolation switch interlock of the utility model has following beneficial effect:
1. this kind of high-voltage switch cabinet isolation switch interlock by active pin block location lockhole do not allow hand-power operating mechanism operate, can pin arbitrarily one of them isolating switch as required makes it be in gate-dividing state, structure is simple, manufacture and easy for installation, safe and reliable, be beneficial to electric power system application;
2. active pin two ends are provided with dog screw, and the insertion position of convenient adjustment active pin, makes interlocking more reliable.
Be described further below in conjunction with the technical characteristic of drawings and Examples to a kind of high-voltage switch cabinet isolation switch interlock of the utility model.

Embodiment
Embodiment
A kind of high-voltage switch cabinet isolation switch interlock, the hand-power operating mechanism 1 comprising isolating switch and the active pin 2 be laterally arranged between two hand-power operating mechanisms; Pedestal 12 waist of described hand-power operating mechanism has and the pin-and-hole 14 of locating lockhole 13 and being communicated with, described active pin 2 is a bar shaped cuboid, in the pin-and-hole 14 that a wherein hand-power operating mechanism 1 is inserted in its one end and location lockhole 13, the pin-and-hole 14 that the other end rides over another hand-power operating mechanism 1 does not insert location lockhole 13.
The two ends, left and right of described active pin 2 are respectively equipped with dog screw 3, described each end dog screw is greater than the distance of locating lockhole 4 to hand-power operating mechanism 1 pedestal outer wall apart from the distance of corresponding active pin 2 termination, when the left end of active pin 2 inserts in the location lockhole of left side hand-power operating mechanism, the dog screw 3 of left end just blocks the pedestal outer wall of left side hand-power operating mechanism, when the right-hand member of active pin 2 inserts in the location lockhole of the right hand-power operating mechanism, the dog screw 3 of right-hand member just blocks the pedestal outer wall of the right hand-power operating mechanism.
Operation principle:
Install about two isolating switch hand-power operating mechanisms.When left side hand-power operating mechanism is in closing position, active pin is stirred left and is inserted in the lockhole of hand-power operating mechanism location, the left side, until the pedestal outer wall that the dog screw of active pin left end just blocks left side hand-power operating mechanism makes pivot pin not be moved to the left again, now the hand-power operating mechanism on the left side can not be shaken hands being separated isolating switch downwards, the other end of active pin then rides on the pin-and-hole of the hand-power operating mechanism on the right, but do not insert in the lockhole of location, now the right hand-power operating mechanism can operate arbitrarily a deciliter isolating switch.Otherwise, if want the hand-power operating mechanism operating left side, must when the hand-power operating mechanism on right side be in closing position, active pin can be stirred to the right to insert in the lockhole of hand-power operating mechanism location, right side and until the dog screw of active pin right-hand member just blocks, pivot pin can not be moved right again, now left side hand-power operating mechanism can operate arbitrarily a deciliter isolating switch, thus realizes the interlocking between two isolating switch hand-power operating mechanisms.
