Abstract

The utility model discloses a bus-bar on high and low voltage switch equipment, comprising copper bars of connecting holes at both ends and a conductive layer which is arranged on the surface of the copper bar. The conductive layer is a nickel plating layer. The structure is adopted. Compared with the prior art, the nickel plating layer decreases the contact resistance of the connecting site of the bus-bar and has stronger oxidation resistance capability. In this way, the problems that the contact resistance of the connecting site of the bus-bar is enlarged, heating quantity is serious and accidents occur because of the extended service of switch equipment are solved. Simultaneously, the surface following effect of an electric conductor is also improved, the heating quantity is further decreased, and energy consumption is lowered. The bus-bar provided with the nickel plating layer is lucent, and the external appearance of product is improved.

Description

A kind of busbar that is used on the high and low voltage switch equipment
Technical field
The utility model relates to high and low voltage switch equipment, specifically relates to a kind of busbar that is used on the high and low voltage switch equipment.
Background technology
At present, below the 35KV, the surface, a busbar junction of the complete inside plant of three-phase alternating current 50HZ high-low pressure mainly contains following several processing mode usually, and 1, the junction removing surface is clean, is coated with neutral vaseline or conducting resinl.2, the junction surface local is warded off tin.3, the junction surface local is zinc-plated.Above-mentioned several method all can not well improve the anodizing on surface, busbar junction, especially after the conducting resinl long-play dries up, increased contact resistance, more can not improve electric conductor surface skin effect, when causing the equipment long-time running, busbar junction contact resistance strengthens, (when ambient temperature 20 is spent, after the long-term use of 100CM * 10CM busbar, applying electric current 100 peace single-point junction loop resistances is 70.93 micro-ohms) generate heat seriously, and easily accidents caused.
The utility model content
Technical problem to be solved in the utility model provides a kind of busbar that is used on the high and low voltage switch equipment, to reach the purpose that reduces busbar junction contact resistance.
The technical solution of the utility model is that a kind of busbar that is used on the high and low voltage switch equipment is included in the copper bar that its two ends are provided with connecting hole, it is characterized in that: the surface of the copper bar that is positioned at is provided with conductive layer.
A kind of busbar that is used on the high and low voltage switch equipment, described conductive layer are nickel coating.Nickel coating has reduced busbar junction contact resistance, and has stronger oxidation resistance.
Owing to adopted said structure, compare with prior art: the surface of the copper bar that is positioned at is provided with conductive layer.Conductive layer is a nickel coating, and nickel coating has reduced busbar junction contact resistance, and has stronger oxidation resistance.Solved the switchgear long-time running like this and caused busbar junction contact resistance to strengthen, heating is serious, accidents caused problem.Simultaneously, also improve the surperficial skin effect of electric conductor, further reduced heating, reduced energy consumption.Be provided with the busbar surface-brightening of nickel coating, improved the outward appearance of product.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below;
Fig. 1 is a kind of busbar structural representation that is used on the high and low voltage switch equipment of the utility model;
Fig. 2 is a kind of busbar cutaway view that is used on the high and low voltage switch equipment of the utility model;
In Fig. 1, Fig. 2,1, connecting hole; 2, copper bar; 3, conductive layer.
Embodiment
As shown in Figure 1 and Figure 2, a kind of busbar that is used on the high and low voltage switch equipment is included in the copper bar 2 that its two ends are provided with connecting hole, and the surface of the copper bar 2 that is positioned at is provided with conductive layer 3, and conductive layer 3 is a nickel coating.Electrical equipment is connected on connecting hole 1 realization by the busbar two ends and power supply and the switchgear.When ambient temperature 20 was spent, 100CM * 10CM surface was provided with the busbar service test of nickel coating, and applying electric current 100 peace single-point junction loop resistances is that 42.97 micro-ohms (containing the copper bar intrinsic resistance) nickel coating has reduced busbar junction contact resistance.
