Technical field
The utility model relates to a kind of protective device secondary pressure plate special error operation locking cover, belongs to electric power system secondary and switches pressing plate protective device.
Background technology
The pressing plate of electric system protection device secondary switching is now divided into two kinds of forms, and one is that secondary switching pressing plate can take off switching pressing plate in the time of dead status, and another kind is that secondary switching pressing plate cannot take off switching pressing plate in the time of dead status.Stop using and protective device while having verifying work at electric system protection device; operations staff should will need the protective device connection of verification jump other operating primary equipment pressing plates and stop using, prevent maintainer's mistake pressing plate is devoted oneself to work and by operating primary equipment tripping operation in the time carrying out protector revise.Because the switching pressing plate of the second situation can not take off from protection screen, this will become a major hidden danger that affects equipment safety operation.
Utility model content
According to above the deficiencies in the prior art; technical problem to be solved in the utility model is: a kind of protective device secondary pressure plate special error operation locking cover is provided; secondary pressure plate and the maintainer that connection can be jumped to operational outfit effectively isolate; prevent misoperation; make whole electric power system reliability service; eliminate safe hidden trouble, use and easy to carry.
Protective device secondary pressure plate special error operation locking cover described in the utility model, formed by left cover and right cover, left cover comprises at least two group cover bodies, wherein, a rear cover body is slidably mounted in last cover body, in the top frame of afterbody cover body, combination hub is housed, four suckers are equipped with respectively in the bight, below of stem cover body; Right cover comprises at least two group cover bodies; Wherein, a rear cover body is slidably mounted in last cover body, in the top frame of afterbody cover body, plug is housed, and four suckers are equipped with respectively in the bight, below of stem cover body.
Single or multiple secondary pressure plates can be covered by left cover or right cover; effectively isolate; coordinate with combination hub by plug; left cover and right cover are coupled together; simultaneously by the slip cover body pull-out in left cover and right cover; the connection that affects maintainer's safety in the protection screen of interruption maintenance can be jumped to whole row's secondary pressure plate of operational outfit and cover, prevent maintainer by secondary pressure plate miscarry into, ensure safety.It is very little, easy to carry that left cover and right cover are packed up rear volume.
Described left cover is made up of the first left cover body, the second left cover body, and the second left cover body is slidably mounted in the first left cover body, in the top frame of the second left cover body, combination hub is housed; Right cover is made up of the first right cover body, the second right cover body, the second right cover body is slidably mounted in the first right cover body, in the top frame of the second right cover body, plug is housed, the second left cover body coordinates with plug by combination hub with the second right cover body, after connection, the length of whole cover body increases, and can cover whole row's secondary pressure plate.
Described left cover is made up of the first left cover body, the second left cover body and the 3rd left cover body, and the 3rd left cover body is slidably mounted in the second left cover body, and the second left cover body is slidably mounted in the first left cover body, in the top frame of the 3rd left cover body, combination hub is housed; Right cover is made up of the first right cover body, the second right cover body and the 3rd right cover body, and the 3rd right cover body is slidably mounted in the second right cover body, and the second right cover body is slidably mounted in the first right cover body, in the top frame of the 3rd right cover body, plug is housed.
Between the front cover body of left cover or right cover and rear cover body, can arrange according to actual needs and be connected multiple cover bodies, multiple cover bodies all can be received in front cover body successively, and volume is reduced, easy to carry, by sucker, cover body are arranged on workbench, fixed stable.
Compared with prior art, the beneficial effects of the utility model are:
Secondary pressure plate and maintainer that this protective device secondary pressure plate special error operation locking cover can be jumped connection operational outfit effectively isolate, and prevent misoperation, make whole electric power system reliability service, eliminate safe hidden trouble, and use and easy to carry; Install and fixation, easy to carry.
