Abstract
The present invention relates to technical field of electric power to be made of more particularly, to a kind of isolating and protecting cover for protective device front panel warning sign, the first support frame, the second support frame.The present invention can provide isolating and protecting for the protective relaying device on protection screen, to prevent from accidentally touching running protective device when having work on same screen, so that relay protection, which occurs, accidentally touches accident.Brief and practical of the present invention has good marketing.
Description
Technical field
The invention belongs to the protective device technical fields of power equipment operation, more particularly, to one kind for before protective device
The isolating and protecting cover of panel.
Background technique
In the power system, protective relaying device is for protecting electric system and its element (generator, transformer, transmission of electricity
Route, bus etc.) it is allowed to from damage, it is the important equipment in substation, safe operation is directly related to power grid or even electricity
The safe operation of Force system.Usually by the protective 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 overhauls, the protective device of maintenance is the same as on screen
When having the protective device of running equipment, just the wrong risk for touching maloperation running equipment protective device, especially there is operation button
Front panel and have the backboard of secondary connection, such as when needing to adjust definite value to the protective device of maintenance maloperation to the guarantor run
On protection unit, or the protective device backboard secondary line of operation is accidentally touched when working on the protective device backboard of maintenance, then pole has
It may cause protection misoperation or tripping, cause the accident and its biggish economic loss, so needing the panel to protective device
Maloperation is accidentally touched when taking isolating and protecting measure with backboard to avoid maintenance with the running protection device on screen.
There are two types of the common protective device isolating and protecting measures in scene at present, and one is will print to be printed on that " operation is set
It is standby " the A4 paper adhesive tapes of printed words is on the protective device panel and backboard of operation, to play warning and prevent the work of maloperation
With defect has: (1) random too many, not beautiful enough after use, " running equipment " printed words that (2) field print comes out are black
Color, it is strong without the warning of red word, the secondary line on backboard may be encountered when (3) are attached on protective device backboard, simultaneously
A4 paper can be also pressed on backboard secondary line, be likely to result in secondary line loosening.Another protective 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 protective device two sides, to play warning
With the effect for preventing maloperation, defect has: (1) the red door curtain made of cloth is opaque structure, and when use can interfere operations staff to observe
The protective device of operation, (2) red door curtain made of cloth are soft material, and operating personnel such as accidentally touches anti-on the door curtain made of cloth in maintenance process
And be easy accidentally to press protected protective device button, it causes in certain risk.
For this purpose, place technical field is expected to occur for protective device panel and can provide preferable warning and prevent to miss
The protective device isolating and protecting cover of operation.
