Description

A kind of new 35KV outgoing line cabinets

Technical field

The utility model belongs to outgoing line cabinet technical field, more particularly, to a kind of new 35KV outgoing line cabinets.

Background technology

In existing technology, 35kV outgoing line cabinets are widely used in power plant, substation and industrial and mineral industry etc., to circuit Control, protection and monitoring function, ensure that its operation stability.Breaker, electric current are generally comprised inside 35kV outgoing line cabinets The elements such as mutual inductor, arrester, because the volume of element is larger, interior in a limited space how reasonable arrangement element is very An important step, it is ensured that the safe distance between each element will also ensure the safe distance between copper bar and electrical equipment, when When space structure is close, heat that when equipment high-speed cruising generates can not shed and can influence the stabilization of equipment, particularly require frame When vacating line, the narrow and small difficulty that can also increase construction in space.

At present, for common cabinet type as shown in Figure 1, current transformer use is general universal, shape is very big, is placed on cabinet Rear lower, the wall bushing of outlet copper bar mouth under breaker access one end of current transformer, from the another of current transformer When bringing out line, to ensure safe distance, to copper bar bending, then supported by insulator, lead to cabinet top, complete overhead outlet.

However this scheme is since current transformer shape is bigger, and bottom is needed to install, so after greatly occupying The confined space of lower part when needing overhead outlet, adds the arrangement difficulty of copper bar, increases its technology difficulty, materials Relative increase.

Utility model content

In view of this, the utility model is directed to a kind of new 35KV outgoing line cabinets, with the deficiency that solves the above problems Place.

In order to achieve the above objectives, the technical solution of the utility model is realized in：

A kind of new 35KV outgoing line cabinets, including cabinet, lower combined instrument transformer, breaker, outlet copper bar, in the cabinet Portion is equipped with the circuit breaker cart room separated with partition plate and bus-bar room, and breaker, the mother are equipped in the circuit breaker cart room Lower combined instrument transformer is installed, one end of the lower combined instrument transformer is equipped with contact box, separately in the middle part of the partition plate of line room one side One end is equipped with the Wiring port perpendicular to axis direction, and towards circuit breaker cart room, the lower combined type is mutual at the contact box end The Wiring port of sensor is set downward, and a contact of the breaker is connected with the contact box of lower combined instrument transformer, The outlet copper bar is stretched out and oppositely extending through at the top of cabinet by the Wiring port of lower combined instrument transformer.

Further, combined instrument transformer is installed on the bus-bar room partition plate above the lower combined instrument transformer, One end of the upper combined instrument transformer towards circuit breaker cart room is equipped with contact box, and the other end is equipped with Wiring port upward.

Further, another contact of the breaker is connected with the contact box of upper combined instrument transformer, described upper group Combined mutual inductor connects busbar by Wiring port.

Further, wall bushing is equipped at the top of the cabinet, the outlet copper bar is by wall bushing at the top of cabinet Outlet.

Further, multiple insulators are connected on the outlet copper bar.

Compared with the prior art, new 35KV outgoing line cabinets described in the utility model have the advantage that：

New 35KV outgoing line cabinets described in the utility model cancel the peace of traditional current transformer and contact of breaker box Dress, but outlet copper bar is connected using the combined instrument transformer with contact box, space availability ratio is considerably increased, increases copper Safe distance of the array pitch from electrical equipment, the difficulty of copper bar manufacture craft when reducing overhead outlet, saves materials, while Heat dissipation and air circulation are accelerated, then moist environment can also stablize use, widened the application field of equipment significantly, made system Operation is more stablized.
