Abstract

The utility model discloses a multi -functional 35kV exchanges lightning combiner box, the insulator is fixed on the inner wall of the left side of box, the right -hand member at the insulator is fixed to the busbar, the hyperbaric chamber is established to right part in the box, the hyperbaric chamber internal door is established to the front side in hyperbaric chamber, establish condensation controller and electromagnetic lock on the internal door of hyperbaric chamber, isolator establishes in the hyperbaric chamber, and after opening, it has visible fracture, it connects isolator to articulate after many cables on the busbar converge, the upper end in the box is established to the sensor. This compactness rational in infrastructure, low in production cost, performance safe and reliable, the appearance is pleasing to the eye, reduces and knots between the cable, makes things convenient for laying of cable.

Description

Multi-functional 35kV communication lightning-protection header box

Technical field

This utility model relates to a kind of communication lightning-protection header box.

Background technology

In the process of construction of new forms of energy power plant, case becomes owing to the advantages such as it is with short production cycle, simple in construction convenience, a less investment are widely applied.But limited space in becoming because of case, in the case of mounting multi-cable, easily causes arcing electric discharge between cable, affects power plant and run normally.Along with photovoltaic generation field capacity is increasing, case becomes series connection number of outgoing and gets more and more, when a case becomes and breaks down, it is difficult to avoid whole piece circuit of need to stopping transport, will result in huge loss.

There is problems in that of existing header box

1, production cost is higher, space hold is relatively big, and high-pressure side is without clearly visible fracture, and case becomes high-pressure side need to mount multi-cable, intersects and cabling is complicated between cable, and the spacing of end electrical body is little, site operation difficulty；

2, multiple stage case becomes and uses a collection electric line concatenation, after in collection electric line, certain case becomes outlet fault, it is necessary to stoppage in transit whole piece collection electric line, and end damage after site examining and repairing difficulty, decrease user and surf the Net selling benefit；

3, between field box becomes, the form of concatenation is complicated, and current collection line construction is difficult and great in constructing amount, and cable laying distance is big, and cost is high.Cannot realize collecting the management that electric line separate unit case becomes.

Summary of the invention

For solving the above-mentioned problems in the prior art, this utility model patent provides a kind of multi-functional 35kV communication lightning-protection header box, and its technical scheme taked is:

Including casing, insulator, bus-bar, sensor, spark gap and disconnecting switch, insulator is fixed in the inner left wall of casing, bus-bar is " M " type, and bus-bar is fixed on the right-hand member of insulator, right part in casing sets altitude chamber, the front side of altitude chamber sets altitude chamber inside door, condensation controller and electromagnetic lock is set on the inside door of altitude chamber, spark gap and disconnecting switch are located in altitude chamber, disconnecting switch has visible fracture after opening, mounting multi-cable on the busbar connects disconnecting switch after confluxing, sensor is located at the upper end in casing, it is furnished with procedure lock on the guidance panel of disconnecting switch.

High-pressure side of the present utility model band disconnecting switch, is divided into two sections by the copper bar in header box, is divided into case to become inlet wire side and collection electric line outlet side, and disconnecting switch can form the most visible fracture after opening, and the convenient case individually stopped transport in collection electric line becomes.Disconnecting switch increases 4F procedure lock, ensure that can only in the case of on-load switch is opened could disconnecting switch operation, header box sets maintenance door simultaneously, and maintenance door is mounted with electromagnetic lock, guarantee the most just to open inside door to enter, it is achieved that electric five prevent chain.High-voltage arrester, compact conformation is installed additional, it is to avoid the lightning ingress damage to equipment in this header box.

Accompanying drawing explanation

Fig. 1 is internal structure schematic diagram of the present utility model；

Fig. 2 is external structure schematic diagram of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described in detail.

As depicted in figs. 1 and 2, insulator 1 is fixed in the inner left wall of casing 9, bus-bar 2 is " M " type, and bus-bar 2 is fixed on the right-hand member of insulator 1, right part in casing 9 sets altitude chamber, the front side of altitude chamber sets altitude chamber inside door 7, condensation controller 5 and electromagnetic lock 6 is set on altitude chamber inside door 7, spark gap 4 and disconnecting switch 8 are located in altitude chamber, disconnecting switch 8 has visible fracture after opening, the multi-cable being articulated on bus-bar 2 connects the output of disconnecting switch 8 to opposite side after confluxing, realize four and enter an effect of confluxing out, not only reduce the radical of mounting cable in case becomes, can also play when line failure, only disconnect associated collection electric line, reduce the power failure range of major loop.Sensor 3 is located at the upper end in casing 9, and the guidance panel of disconnecting switch 8 is furnished with procedure lock.Whole header box is rational in infrastructure compact, and production cost is low, and performance safety is reliable, good looking appearance, the design of convenient collection electric line and planning, makes whole current collection line clear reasonable, reduces and tie a knot between cable, facilitate laying of cable.
