Along with the development of science and technology, electric power resources are widely used, and therefore, along with the trend, high-voltage electric equipment also starts to emerge and improve greatly. Junction boxes are an essential infrastructure in high-voltage electrical equipment. The junction box is a switching construction line, marks branch lines, and provides a convenient interface device for wiring and line inspection. The junction box that uses at present adopts the closed secondary junction box that iron made mostly, and this kind of junction box is because long-term operation in outdoor abominable operational environment for it is serious to go up mutual MWB mutual-inductor iron secondary junction box corrosion, and inside seal inefficacy causes the incasement wiring terminal to be corroded seriously, has serious potential safety hazard to equipment safe operation. In the prior art, the replacement of the junction box is very complicated, and the high-voltage electrical equipment needs to be integrally tested every time of replacement, so that new operation can be put into operation. Under the prerequisite of not changing the box, can only carry out interim processing through the parcel to the box outside, but rain-proof effect is not good and the operation is inconvenient.

SUMMERY OF THE UTILITY MODEL

In order to overcome the shortcomings and shortcomings of the prior art, the utility model provides a secondary junction box which is convenient to wire, convenient to disassemble, safe and reliable.

In order to solve the technical problem, the utility model discloses take following scheme: a secondary junction box comprises a junction box cover, a junction box body and hasps arranged on two sides of the junction box, wherein the junction box body is connected with the junction box cover in a hasp type; the center of the lower part of the wiring box body is provided with a wire inlet hole for accessing an external equipment circuit, and the bottom of the wiring box body is provided with a stainless steel aluminum plate fixing plate arranged in the wire inlet hole at the bottom;

Furthermore, a wire hole of a grounding wire is arranged on the surface of the wiring box cover.

furthermore, two sides of the bottom of the junction box are respectively provided with secondary junction box air vents.

Furthermore, two sides of the bottom of the junction box are respectively provided with a secondary junction bar and a control line, and the two junction bars are arranged side by side.

By adopting the technical scheme, the beneficial effects of the utility model are that: the hasp is arranged on the two sides of the box body, so that the box cover and the box body are connected in a hasp type, the defect that the box cover and the box body are not detachable due to integral synthesis is overcome, and the box cover can be more conveniently replaced and detached; the secondary row wiring is arranged in the box body, so that the secondary row wiring can be more stably fixed on the mutual inductor, and a control wire can be arranged to fix an instrument and a meter entering the transformer substation; the bottom of the box entrance hole for insert the external equipment circuit, use stainless steel aluminium sheet to consolidate the terminal box, make the staff can directly change in the junction box, it is more convenient to install. The utility model discloses the secondary junction box has adopted stainless steel mass energy to reduce the corruption on surface, has carried out the simplification of certain degree on installation and follow-up work, has guaranteed the reliable operation of equipment simultaneously.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the provided drawings without creative efforts.
