Abstract

The utility model discloses a sealing surface structure of electric power equipment. The electric power equipment structure comprises a vacuum explosion chamber solidified by an epoxy resin coating layer and breaker related conductive parts; and the external surface of the epoxy resin coating layer forms an accidented rough surface. According to the utility model, the accidented rough surface is formed on the sealing surface of the electric power equipment to increase surface creep distance between leading-out terminals and between the leading-out terminal and the ground under a same machinery dimension, so as to maintain high power frequency tolerance voltage and thunder impact tolerance voltage of seal pole columns under severe conditions, improve field distribution on the outer surface of the seal pole column and enhance dielectric strength of the air; meanwhile, matt surface effect formed by the rough surface can increase appearance qualitative sense of the product.

Description

Power equipment seals surface texture admittedly

Technical field

The utility model is to seal product admittedly about a kind of power equipment, refers to that especially a kind of power equipment seals surface texture admittedly.

Background technology

Pole is that the conductive pieces that vacuum interrupter is relevant with circuit breaker is embedded into simultaneously in the easy cured solid insulating material of this class of epoxy resin and forms pole, makes whole circuit breaker polar become as a whole parts.It has three advantages: the one, and modularized design, simple in structure, detachable part is few, the reliability height; The 2nd, high insulating bar ability, it becomes surface insulation into the volume insulation, compares air insulation, has reduced the influence of environment, has improved dielectric strength greatly; The 3rd, the circuit breaker size is dwindled, be conducive to the switch cubicle miniaturization.

And this series products seals the surface admittedly and is wet look at present, and it is fast therefore can to exist surperficial air to flow, between the leading-out terminal and leading-out terminal liftoff between the short problem of relative distance, industrial frequency withstand voltage relative under same mechanical dimension is little, and then influences the insulation property of product; Appearance tactile impression is common simultaneously.

The utility model content

The purpose of this utility model provides a kind of pole that can effectively improve and keeps higher power-frequency withstand voltage and the power equipment of lightning impulse withstand voltage to seal surface texture admittedly under mal-condition.

For achieving the above object, solution of the present utility model is:

A kind of power equipment seals surface texture admittedly, and this power equipment structure comprises vacuum interrupter and the relevant conductive pieces of circuit breaker that the epoxy resin coating layer solidifies; Wherein: the outer surface of this epoxy resin coating layer forms concavo-convex matsurface.

After adopting such scheme, the utility model forms the matsurface with concaveconvex structure by seal the surface admittedly at power equipment, can improve between the same mechanical dimension lower wire end and the surperficial creep distance of leading-out terminal between liftoff, under mal-condition, keep higher power-frequency withstand voltage and lightning impulse withstand voltage to satisfy pole, and improve the Electric Field Distribution of pole outer surface, strengthen airborne dielectric strength; The mute optical surface effect of matsurface formation simultaneously can improve the appearance tactile impression of product.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the partial enlarged drawing of Fig. 1.

Embodiment

Explain execution mode of the present utility model below in conjunction with accompanying drawing:

As shown in Figure 1, 2, the utility model has disclosed a kind of power equipment and has sealed surface texture admittedly, and this power equipment structure comprises that epoxy resin coating layer 1 and epoxy resin coat vacuum interrupter and the relevant conductive pieces of circuit breaker that solidifies; Its practical novel key is:

The pit that distributes at the outer surface of this epoxy resin coating layer 1 is or/and protruding grain 11, form rough matsurface lines with the solid envelope surface that makes this power equipment, adopt rough surface to handle between the leading-out terminal that can improve under the same mechanical dimension and the surperficial creep distance of leading-out terminal between liftoff, high-quality appearance tactile impression.Satisfy pole and under harsh conditions, kept higher power-frequency withstand voltage and lightning impulse withstand voltage, and improved the Electric Field Distribution of pole outer surface, strengthened airborne dielectric strength.

Claims

1. a power equipment seals surface texture admittedly, and this power equipment structure comprises vacuum interrupter and the relevant conductive pieces of circuit breaker that the epoxy resin coating layer solidifies; It is characterized in that: the outer surface of this epoxy resin coating layer forms concavo-convex matsurface.
