Description
Technical field
The utility model relates to the anti-CT open circuit of a kind of outdoor aerial line connector.
Background technology
In power industry, its secondary side does not allow open circuit during the current transformer operate as normal, in case open circuit then can produce high pressure at its secondary side can cause the current transformer insulation damages even the instrument transformer blast takes place, will bring injury to operating personnel when serious.And the current 10KV outdoor aerial transmission line that is used for, the miniaturization of anti-Current Transformer Secondary side open circuit, practical device also do not use.
Further expansion along with the urban distribution network automaticity; to there be a large amount of electric power monitorings and electrical protection apparatus to be installed on the 10KV transmission line; and nearly all power equipment all makes Current Transformer gather line current; in the case; indivedual power equipments break down needs maintenance or replacing; the circuit at the necessary usually tripping operation faulty equipment of power department place; to guarantee operator safety; but the negative effect that brings is: large-area power-cuts; bring harmful effect to power supply department, brought the certain economic loss to the user.So prior art exists not enough: in the 10Kv transmission line, instrument transformer is because of no open-circuit-protection, so instrument transformer burns easily and the explode maintenance or the replacing of power equipment simultaneously need just can overhaul this line tripping or change.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and instrument transformer is not easy to burn or the maintenance of blast, power equipment or change does not need this line tripping just can be realized the anti-CT of a kind of outdoor aerial line that overhauls or the change connector of opening a way because of secondary side open circuit when providing a kind of.
The technical scheme that the utility model adopted is: the utility model comprises plug, socket, described plug comprises insulation shell, four connect jack, swivel nut, fastening clip for cable, described connection jack is connected with the cable soldering opening, be provided with four in the described socket and connect contact pin, described connection contact pin is provided with the cable soldering opening, described connection jack is with described to be connected contact pin suitable, also be provided with four fore-sets on the described socket, the junction of described plug and described socket is provided with sealing gasket, described plug inside is provided with four springs, each described spring one end all is connected with the short circuit post, and described short circuit post contacts with described fore-set.
Each described spring is evenly distributed between four described connection jacks.
Described short circuit post is cylindrical.
The beneficial effects of the utility model are: because the utility model comprises plug and socket; described plug comprises four described connection jacks; four described springs; four described short circuit posts; each described spring one end all is connected with a described short circuit post; described socket is provided with four fore-sets; when described plug is connected with described socket; four described fore-sets contact with four described short circuit posts and described spring are compressed; make described short circuit post disconnect with the described jack that is connected; when described plug separates with described socket; four described short circuit posts respectively under the effect of described spring with two adjacent described connection jack short circuits; so behind use the utility model; the normal operation of outdoor aerial circuit just often; if breaking down, indivedual basic routing lines on this circuit or branch line measure and control device or line protective devices need maintenance or replacing; power supply department need not this line tripping; the maintenance or the replacing of fault power equipment be can carry out, outdoor aerial line current instrument transformer secondary side stube cable and electric device also can be reduced because of vibrations or wave the instrument transformer that the plug and socket uncoupling that causes caused and burn and explosion accident.
