Description
Technical field
The invention belongs to the protection device technical field of power equipment operation, it is used for more particularly, to one kind after protection device
The isolating and protecting cover of panel.
Background technology
In power system, protective relaying device is used to protect power system and its element（Generator, transformer, transmission of electricity
Circuit, bus etc.）It is allowed to exempt from infringement, is the visual plant in transformer station, its safe operation is directly connected to power network or even electricity
The safe operation of Force system.Usually by the protection device of different interval on the same face protection screen in existing Substation Design,
To save space and screen cabinet expense, but in maintenance, when especially monospace is overhauled, its protection device overhauled is with screen
When having the protection device of operational outfit, just the wrong risk for touching maloperation operational outfit protection device, especially there is operation button
Front panel and have the backboard of secondary connection, maloperation is to the guarantor run during than adjusting definite value if desired for the protection device to maintenance
On protection unit, or the mistiming that works on the protection device backboard of maintenance touches the protection device backboard secondary line of operation, then pole has
Protection misoperation or tripping are likely to result in, is caused the accident and its larger economic loss, so needing the panel to protection device
Isolating and protecting measure, which is taken, with backboard touches maloperation with the running protection device on screen to avoid overhauling mistiming.
The conventional protection device isolating and protecting measure in scene at present has two kinds, and one kind is will to print to be printed on that " operation is set
It is standby " the A4 paper adhesive tapes of printed words is on the protection device panel and backboard of operation, with the work for playing warning and preventing maloperation
With its defect has：（1）It is random too many, it is not attractive in appearance enough after use,（2）" operational outfit " printed words that field print comes out are black
Color, the warning without red word is strong,（3）The secondary line on backboard may be encountered by being attached to when on protection device backboard, simultaneously
A4 paper can be also pressed on backboard secondary line, be likely to result in secondary line loosening.Another protection device isolating and protecting measure is
The red door curtain made of cloth of correspondingly-sized is made, four angle magnet can be adsorbed on the iron plate of protection device both sides, to play warning
With the effect for preventing maloperation, its defect has：（1）The red door curtain made of cloth is opaque structure, operations staff can be hindered to observe when using
The protection device of operation,（2）The red door curtain made of cloth is soft material, and operating personnel is in maintenance process as imprudence is encountered on the door curtain made of cloth instead
And protected protection device button easily is pressed by mistake, cause in certain risk.
Therefore, place technical field is expected to occur being used for protection device panel and can provide preferably warning and prevent to miss
The protection device isolating and protecting cover of operation.
The content of the invention
To solve the above problems, it is an object of the invention to provide a kind of isolating and protecting for protection device rear board
Cover, it is realized using following technical scheme.
In the embodiment 1 of the present invention, a kind of isolating and protecting cover for protection device rear board, it is characterised in that by two
