Abstract
The utility model discloses a special junction box for electric energy metering secondary loop which comprises an independent and detached junction box for electric voltage secondary loop and a junction box for current secondary loop. The junction box for electric voltage secondary loop is provided with a phase wire junction block and a zero line junction block which are mutually insulated and detached. A bolt fastening fuse is connected between the corresponding phase wire junction block, and the side wall of the box body corresponding to the junction block is provided with a connection hole. The junction box for current secondary loop is provided with a junction block and a short circuit connective sliding blade which are mutually insulated and detached. The side wall of the box body corresponding to the junction block is provided with a connection hole, and every junction block is provided with a binding post screw. Two junction box for secondary loop can be respectively sealed by making use of the utility model, which can effectively prevent the occurrence of the stealing electricity behavior. When the electric voltage junction or the current junction in the secondary loop need independently adjust, the corresponding junction box can be independently unsealed with convenience, which is convenient to distributing the different junction boxes unsealing right for the current supply branch and the user.
Description
Technical field the utility model relates to a kind of electric energy metrical special junction box, specifically is used for the special junction box of electric power meter secondary circuit.
Background technology its structure of electric energy metrical special junction box (also claiming the associating terminal box) commonly used at present comprises box body and lid, has voltage terminal, electric current splicing ear to be connected slide plate with short circuit in the box body, and three kinds of routes of its collection are connected in one.Owing to adopted embedded safety fuse in the voltage wiring, thereby be easy to generate shortcomings such as loose contact and pressure drop loss are too big.The voltage wiring connects because of adopting wiring pile (bolt) and screw connecting mode, and not only pressure drop is big, and heating easily.And too big pressure drop loss can have influence on the reliability service of secondary circuit.Simultaneously, because voltage wiring and electric current wiring all are set together, thereby can only the butted line box carry out integral body and seal up, like this, power supply department and user voltage wiring and the electric current wiring when regulating in butted line box respectively, just can not distinguish is that what person's butted line box is broken seal actually.In addition, the secondary circuit after being picked out by terminal box just can not prevent the generation of stealing electricity phenomenon effectively, thereby cause the power supply department property loss owing to can't seal up respectively.
The summary of the invention technical problem to be solved in the utility model is to propose a kind of pressure drop that can effectively reduce in the secondary circuit, guarantee the secondary circuit reliability service, and can realize voltage wiring in the secondary circuit is connected the electric energy metering secondary special junction box of sealing up respectively with electric current.
For solving the problems of the technologies described above, the utility model electric energy metering secondary special junction box comprises the voltage secondary circuit terminal box and the electric current secondary loop terminal box of independently separating, be provided with phase line tagblock and the zero line tagblock that mutually insulated separates in the described voltage secondary circuit terminal box box body, the cross section of described phase line tagblock is step-like, be connected with bolt between each corresponding phase line tagblock and connect fuse, be provided with wiring hole corresponding to the tagblock place on the described box side wall; Be provided with the tagblock that mutual insulation separates in the described electric current secondary loop terminal box box body and be connected slide plate with short circuit, be provided with wiring hole corresponding to the tagblock place on the box side wall, above-mentioned each tagblock is provided with terminal screw.
The utility model is owing to adopted above-mentioned technical pattern, during use, the electric current wiring and the voltage wiring that will pick out from the associating terminal box insert the utility model electric current secondary loop terminal box and voltage secondary circuit terminal box respectively, and two terminal boxes are placed respectively in the CT of transformer station device terminals case and the PT device terminals case.Like this, just can seal up respectively, can effectively prevent the generation of electricity filching behavior these two secondary circuit terminal boxes.In the time of need regulating separately voltage wiring in the secondary circuit or electric current wiring,, also be convenient to power supply department and user and distribute the different terminal boxes authority of breaking seal as long as the corresponding terminal box of unpacking separately is very convenient.In the voltage terminal box cross section of phase line tagblock is made as step-likely, just can reduces the pressure drop loss during wiring without wiring pile (bolt) screw connecting mode.Equally, connect fuse with bolt between corresponding tagblock and link to each other, not only make between tagblock to contact well, and can reduce the pressure drop loss, guarantee the secondary circuit reliability service.
Description of drawings is described in further detail the utility model below in conjunction with drawings and embodiments.
Fig. 1 is the structural representation of electric current secondary loop terminal box in the utility model;
Fig. 2 is the structural representation of voltage secondary circuit terminal box in the utility model;
Fig. 3 is the outer shape synoptic diagram that bolt connects fuse;
