Abstract
The utility model discloses a pressure plate isolation hood for relay protection, which comprises a front baffle plate and a bracket arranged around the front baffle plate, wherein the bracket is vertical to the front baffle plate; the bottom surfaces on the left side and the right side of the front baffle plate are provided grooves; and magnets are arranged in the grooves. An identification label is pasted on the front baffle plate, and a caution strip is pasted on the periphery of the front baffle plate. The pressure plate isolation hood can effectively isolate an operating loop, is steady and reliable, and is difficult to fall off; besides, the pressure plate isolation hood can effectively prevent on-site staffs from causing accidents due to error touches and maloperation in the working process, and can facilitate the observation of the working condition of the operating loop by adopting a smooth and transparent insulating material with mirror-face-grade degree of finish.
Description
Technical field
The utility model relates to a kind of cage, particularly a kind of protection pressing plate cage that is used for relay protection of power system.
Background technology
The relaying protection of power industry is a job of paying special attention to all the year, and reminds people is observed the safety rule system constantly, carries out operation according to operational procedure.At the relaying protection operation field; often relate to a plurality of operating loops during overhaul of the equipments; for preventing personnel's misoperation; the general red cloth curtain that adopts is isolated operating loop; but this kind measure is difficult for fixing, easily coming off; and wrong in the course of the work risk of bumping, be unfavorable for the site safety operation, need further to improve perfect.
The utility model content
The utility model technical issues that need to address provide a kind of protection pressing plate cage of protective relaying device, and the same screen of the protective relaying device of power industry is arranged that the pressing plate of operation carries out security protection, avoids having an accident in the maintenance maintenance operation process.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of relay-protection pressing plate cage comprises front apron and is arranged on front apron support all around that support is vertical with front apron to be provided with, and magnetite is set on the support.
Further concrete structure of the present utility model is: the support bottom surface of the described front apron left and right sides is provided with groove, and magnetite is arranged in the groove.
Further improvement of the utility model is: described front apron posts mark label, and its periphery posts the caution bar.
Owing to adopted technique scheme, the obtained technological progress of the utility model is:
Result of use of the present utility model is directly perceived, eye-catching, and reliable, difficult drop-off simple to operate, fixing.During stopping transport respectively at same protection screen cabinet different circuit, operating loop is taked reliable isolation, but active zone divides operation and inoperative device.Solved original employing red cloth curtain and isolated and come off easily and nonstandard many drawbacks, and prevented effectively in the implementation that field personnel's mistake is bumped or the accident of misoperation and then initiation takes place.Support around the cage can also prevent that foreign matter is fallen in the protection screen cabinet in the maintenance operation process.
