Description
Technical field
The present invention relates to a kind of hard pressing plate verification auxiliary control device of substation.
Background technology
In recent years, with the extensive expansion of power grid construction, worked extra shifts or extra hours into the work normality of relay protection personnel, very
To the phenomenon for occurring causing substation's delay to put into operation due to secondary device checking and accepting progress issue.
At present, for the secondary service personnel of power transformation when pressing plate correctness is verified, the method taken is mainly single pressing plate
The method that throwing (moving back) while other pressing plates move back (throwing).Assuming that there is 5 hard pressing plates, in two steps, the first step is just for first pressing plate of verification
Verification puts into No. 1 pressing plate, remaining 4 pressing plate (2,3,4, No. 5) exits, and No. 1 pressing plate is exited in second step conversion check, remaining 4
(2,3,4, No. 5) inputs of a pressing plate, positive and negative authentication can confirm that errorless, remaining pressing plate verification method is same.Thus there is
The problem of hard pressing plate verification inefficiency, cost is excessive.
The content of the invention
The object of the present invention is to provide a kind of hard pressing plate verification auxiliary control device of substation, the hard pressing plate school of existing substation is solved
During testing, there is verification inefficiency, cost is excessive the problem of.
The technical solution adopted by the present invention to solve the technical problems is：A kind of hard pressing plate verification auxiliary control device of substation,
Including housing, control mainboard, and the accessory power supply that control mainboard circuit connects are provided with housing, is set in control mainboard
There are one group of button and one group of metal-oxide-semiconductor, button and metal-oxide-semiconductor, which correspond, to be set；One to connect with control mainboard is provided with housing
Jack is organized, connector, the plug-in type connection terminal that connector includes and jack is adapted, plug-in terminals are provided with jack
One group of two connecting line is provided with son, the other end of connecting line is provided with Miniature tack crocodile clip, and Miniature tack crocodile clip covers
It is stamped insulation sleeve.
Further, button selects the upright post type button of tape light.
Further, accessory power supply is provided with city and is electrically accessed socket, switch power module, voltage reduction module and voltage stabilizing chip.
Further, metal-oxide-semiconductor selects IPFP450 type metal-oxide-semiconductors.
Further, function key and one group of relative keys associated with function key are additionally provided with housing, one in relative keys
Divide and button is associated, another part is correspondingly arranged on associated custom block, custom block；When function key is not pressed
When, then it is single control pattern；During function key pressing, then corresponding more control patterns are transferred to.
Beneficial effects of the present invention：The checking time of the hard pressing plate of protective device can be greatly decreased in this auxiliary control device, also
Shorten operation construction period.Exemplified by becoming the verification of 1# main transformer protections by 220kV virtues village, it is about under 1# main transformer load normal conditions
42MW, average each device checking procedure compare shortening 12 minutes, and the work that group is present with mode 31 described in document minute
Make method 41 minutes compared to shortening 23 minutes.In such manner, it is possible to less 23 minutes, that is, reduce loss 16100KWh.With the city
0.56 yuan/kWh of average electricity price is calculated, and can reduce 0.56 × 16100=9016 of loss members, device is by group oneself design group
Dress, about 1000 yuan or so of material acquisition expenses, subtracts material acquisition cost 9016-1000=8016, even if only verifying one
Device, it is possible to reduce the electricity charge loss be 8016 yuan.One transforming plant protecting device quantity has very much, it can be seen that it is economical
Benefit is very considerable.
Below with reference to drawings and examples, the present invention is described in detail.
Brief description of the drawings
