The accidents such as power supply area large-area power-cuts, system sectionalizing are sent out, weight huge economic loss and undesirable social influence are brought.Therefore,
Ensure that the connection validity of electric power relay protection measure and control device hard pressing plate has great significance.
Since the pedestal of the hard pressing plate used in current substation is provided with 4 jacks, two of them are containing metal contact
Jack, two for insulation jack.Two of pedestal connect secondary circuit inside the jack containing metal contact, two are touched containing metal
The jack of head is located at same straight line, and insulation jack is located at another straight line, and it is in X shape that two straight lines, which intersect,.Currently used pressing plate is shape
Shape is rectangle, and both ends are provided with metal contact, are electrically connected inside two metal contacts.When pressing plate is in investment state
When, metal contact is inserted into the jack of two metal contacts of pedestal, and the exposure of insulation jack is in air.Shape is exited when pressing plate is in
When state, metal contact is inserted into two insulation jacks of pedestal, and two jacks containing metal contact are all directly exposed to air.
The metal that the metal contact of general pedestal uses all is pure cu conductor, and exposure is easy to oxidize in air, is formed and is aoxidized on surface
Film.Especially when pressing plate be in for a long time exit state when, the metal contact of the jack of pedestal corrode in air aoxidize it is more serious,
Lead to poor contact.
Summary of the invention
Shape is exited in order to overcome jack of the hard pressing plate pedestal containing metal contact used in current substation to be in pressing plate
It is directly exposed in air when state, corrosion aoxidizes serious defect, and the utility model proposes a kind of secondary circuit hard pressing plate, this realities
With novel the technical solution adopted is that:
A kind of secondary circuit hard pressing plate, including pressing plate ontology and the first metal contact being arranged on pressing plate ontology, second

On body end A, end B, the hard pressing plate further includes having the first blind plug, the second blind plug, the first blind plug, the second insulation
Plug is separately positioned on opposite pressing plate body end C, end D.
Secondary circuit hard pressing plate use state provided by the utility model is divided into investment state and exits state, the pressure
Plate body end A, the position of B is held to correspond to two jacks containing metal contact on pressing plate pedestal, pressing plate body end C, the position for holding D
Two insulation jacks on corresponding pressing plate pedestal.The first metal touching when secondary circuit hard pressing plate is investment state, on pressing plate
Head, the second metal contact are inserted into two jacks with metal contact on pedestal, and the insulation jack on pedestal is exposed, on pressing plate
Blind plug is exposed；The first insulation contact, the second insulation touching when secondary circuit hard pressing plate, which is converted to, exits state, on pressing plate
Head is inserted into two jacks with metal contact on pedestal, and the first metal contact, the second metal contact on pressing plate are inserted into pedestal
On two insulation jacks.
Preferably, it is provided with support column in the middle part of the pressing plate ontology, while pressing plate pedestal offers pressing plate mounting hole.
Preferably, first metal contact, the second metal contact are copper.
Preferably, the pressing plate ontology uses rigid insulation plastics.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
A kind of electric power secondary circuit hard pressing plate provided by the utility model, it is hard to press when pressing plate is investment or exits state
The metal contact of the connection secondary circuit of plate effectively and air insulated can prevent corrosion, oxidation, to solve the company of hard pressing plate
Connect poor contact phenomenon caused by the metal contact corrosion oxidation of secondary circuit.
