Description
Technical field
The utility model relates to a kind of terminal box, especially relates to a kind of 35KV and above measuring apparatus special junction box.
Background technology
Conventional electric energy metrical special junction box (also referred to as combined connection box) at present, its structure comprises box body and lid, is provided with voltage wiring terminal, current wiring terminal and connection slide plate in box body.Large user's electric energy meter field inspection work is one of important site test work of measurement centre, and when field-checking wiring, tester electric current line is easily received combined connection box voltage wire hole, causes security incident.
Combined connection box voltage regime adopts the design of " entrance hole, three wire holes ", and at present due to loss-voltage timers being no longer installed, measuring apparatus one general configuration " electric energy meter+negative control terminal " or " electric energy meter+specially transformer terminals ", therefore only need draw one to two pressure-wire in the every phase in combined connection box place, certainly will cause combined connection box to have one to two vacant wire hole.In the time of electric energy meter field inspection work wiring, because vacant voltage wire hole is close to adjacent phase tester electric current wiring hole, if the situation such as site environment is dim easily causes tester electric current wiring pile crown to receive vacant voltage wire hole and cause security incident in addition.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of 35KV and above measuring apparatus special junction box in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: a kind of 35KV and above measuring apparatus special junction box, comprise box body and lid, it is characterized in that, also comprise detachable insulation stopple, in described box body, be provided with electric current tagblock and voltage tagblock, electric current tagblock is provided with electric current wiring hole, and voltage tagblock is provided with voltage wiring hole, described voltage wiring hole is provided with multiple, has at least and in a voltage wiring hole, adds detachable insulation stopple.
Described detachable insulation stopple comprises the cylindrical shape chock plug that top cover and top cover below arrange, and wherein cylindrical shape chock plug is provided with two circle boss, mates clamping with described voltage wiring hole.
Described electric current tagblock is provided with nine, and every three is one group, is separately positioned on three of the left, center, right of box body; Each electric current tagblock both sides are equipped with a voltage tagblock.
Single current tagblock is provided with 6 row's electric current wiring holes, and both sides four are arranged and are respectively provided with 3 electric current wiring holes, and middle two rows are respectively provided with 2 electric current wiring holes.
Single voltage tagblock is provided with 6-11 voltage wiring hole.
On three voltage tagblocks, be respectively provided with 2 detachable insulation stopples.
Described box body both sides are provided with the connecting hole that connects box body and lid.
Described lid is totally-enclosed cover cap.
Combined connection box end seat adopts polyphosphazene polymer carbonic ester insulating material note system to form.
Voltage hole insulation stopple adopts black PVC injection molding.
Compared with prior art, the utility model combined connection box should be easy for installation, and good looking appearance is rational in infrastructure.Vacant voltage wire hole uses detachable insulated hole to fill in row shutoff, can effectively prevent that tester electric current wiring pile crown from receiving vacant voltage wire hole and causing security incident.Combined connection box end seat adopts polyphosphazene polymer carbonic ester insulating material note system to form simultaneously.Voltage hole insulation stopple adopts black PVC injection molding, can the spontaneous combustion owing to touching overheated live part.These parts that contact with live part meet glow wire test's condition (seeing GB5169.4), and test temperature is+650 DEG C.Hot line can contact with arbitrary position.
