Abstract
The utility model relates to a high-voltage combined junction box, comprising a box body and a box cover, wherein a current wiring block and a voltage wiring block which are insulated from each other are arranged in the box body, the current wiring block and the voltage wiring block are provided with wiring holes, the side wall of the box body is provided with at least two voltage wire outgoing holes corresponding to the voltage wiring block, and the two voltage wire outgoing holes are provided with detachable insulating hole plugs. Compared with the prior art, the high-voltage combined junction box has the advantages of convenient installation, beautiful appearance, reasonable structure and the like.
Description
Technical field
The utility model relates to a kind of terminal box, especially relates to a kind of high pressure combined connection 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 high pressure combined connection 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 high pressure combined connection box, comprise box body and lid, in described box body, be provided with electric current tagblock and voltage tagblock that mutually insulated separates, described electric current tagblock and voltage tagblock are provided with wiring hole, it is characterized in that, the corresponding box side wall of described voltage tagblock is provided with at least two voltage wire holes, and wherein two voltage wire holes are provided with detachable insulation stopple.
Described electric current tagblock and voltage tagblock are equipped with multiple, and each electric current tagblock and voltage tagblock are crisscross arranged, and are provided with dividing plate between adjacent current tagblock and voltage tagblock.
Described electric current tagblock is provided with 2～6, and described voltage tagblock is provided with 2～6.
Described box body both sides are provided with the connecting hole that connects box body and lid, and the mounting hole of terminal box is installed.
Described box side wall is provided with the dovetail groove of pegging graft with 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.
Brief description of the drawings
Fig. 1 is the utility model terminal box body schematic diagram.
