Abstract

The utility model relates to a busbar used for power transmitting, covered with an insulator which is made of silicon rubber. Due to the good electric and physical property of silicon rubber, the busbar covered with the silicon rubber can work safely for a long time at high temperature, with the heat-stable current of 20000A, 2s, which is sufficient to meet relevant national safety standards. The space between busbars can be reduced relatively, thereby, compared to the busbar of prior art, the size of the electric equipment in which the busbar is used is relatively small; in addition, due to the silicon rubber, the busbar can be shaped like a ''N'' so that the size of electrical equipment can be reduced as well as the national safety requirements can be met.

Description

A kind of bus

Technical field

The utility model relates to a kind of bus in order to the conveying electricity consumption in the transmission facility.

Background technology

In the 10KV electric power system, using various metal closed switch cabinets in a large number.Along with scientific and technological progress, its profile is tending towards miniaturization, is conductive carrier as main bus bar, is applied in each switch cubicle, because of security needs, between the electric conductor of three-phase A, B, C enough mounting distances must be arranged.If naked electric conductor is then alternate, relatively the air gap is not less than 125mm.In switch cubicle, lay three-phase bus and need take, cause the volume of transmission facility bigger, the unit cost height than large space, in addition, in order to reach national security requirement, the profile of its bus generally is to adopt a straight line, seldom crooked, the volume of transmission facility is increased.

The utility model content

The purpose of this utility model is to provide a kind of can satisfy national security requirement, the bus that the volume of switch cubicle is reduced.

For achieving the above object, embodiment of the present utility model is: a kind of bus, its bus bulk is provided with an insulator outward.

Described a kind of bus, its insulator are silicon rubber.

Described bus bulk is configured as ㄇ shape.

After adopting said structure, in use, owing to be provided with silicon rubber in the periphery of bus bulk, and silicon rubber has good electric and physical property, makes the bus can be in the work of long-term safety under the hot conditions, and its heat-stable current reaches 20000A, 2 seconds, so it is satisfying national desired safety standard simultaneously, spacing between bus can reduce relatively, and therefore with respect to original bus, the volume of the transmission facility at its place is less; In addition, because the existence of silicon rubber, it is gone back bendable and is converted into ㄇ shape, like this purpose that reduces with regard to the volume that has more reduced the volume of transmission facility, reached to make transmission facility again when satisfying national security requirement.

Description of drawings

Fig. 1 is the structural representation in the utility model cross section;

Fig. 2 is an outside drawing of the present utility model.

Embodiment

As shown in Figure 1, 2, the utility model discloses a kind of bus that is applied in the transmission facility, be provided with an insulator 2 outside its bus bulk 1, wherein:

Described insulator 2 is a silicon rubber, and bus bulk 1 is configured as ㄇ shape.

In use, owing to be provided with silicon rubber 2 in the periphery of bus bulk 1, and silicon rubber 2 has good electric and physical property, make the bus can be in the work of long-term safety under the hot conditions, its heat-stable current reaches 20000A, 2 seconds, so it is satisfying national desired safety standard simultaneously, the spacing between bus can reduce relatively, therefore with respect to original bus, the volume of the transmission facility at its place is less; In addition, because the existence of silicon osmanthus rubber 2, it is gone back bendable and is converted into as shown in Figure 2 appearance, has so just more reduced the volume of transmission facility.

Claims (3)

1. bus, it is characterized in that: its bus bulk is provided with an insulator outward.

2, a kind of bus as claimed in claim 1 is characterized in that: described insulator is a silicon rubber.

3, a kind of bus as claimed in claim 1 or 2, it is characterized in that: described bus bulk is configured as ㄇ shape.
