Description
The present invention relates to a kind of switching device, be specifically related to a kind of novel switched pole.
Background technology
Along with electrical technology constantly develops, a lot of electric equipment develops toward intelligent direction, such development trend requires that the enterprise producing electric equipment improves constantly self research and development ability, design the electric equipment of high-quality, pole switch uses very general in power industry, switch pole be all be used in outdoor, outdoor operational environment like this makes switch pole often occur damaging, once switch pole goes out to damage, the all standing of switchgear will be caused, bring out the appearance of short circuit phenomenon, be short-circuited the scene that switch will be caused to occur spontaneous combustion, current switch pole sealing property is on the market poor, easily allow in switch pole and enter moisture, moisture can cause the corrosion of pole inside for a long time in switch pole, occur that the switch pole result of use of corrosion reduces greatly, serious may cause fractureing of switch pole, cause the decline of switch pole insulation property, bring out security incident.
Summary of the invention
The object of this invention is to provide a kind of structure simple, the novel switched pole of one of good seal performance.
Technical scheme of the present invention is: a kind of novel switched pole, comprise pole housing, insulating element, current transformer, full skirt is provided with outside described pole housing, described full skirt adopts the pattern arrangement that one is long and the other is short separately, described pole enclosure interior is provided with insulating cylinder, point high potential and earth potential in described insulating cylinder, interior full skirt is provided with between described high potential electronegative potential, described interior full skirt adopts integral molding techniques, insulating element is provided with bottom described interior full skirt, insulated tension pole is provided with in described insulating element, described insulated tension pole adopts bellow seal structure, described interior full skirt top is provided with vacuum interrupter, described current transformer adopts punching current transformer, through pole line-outgoing arm in the middle of described current transformer, described pole line-outgoing arm top is provided with fixture block, pole line-outgoing arm clamps by described fixture block, described current transformer is divided into inner circle and cylindrical, taper sheath is formed between described current transformer inner circle and pole line-outgoing arm, described current transformer and pole housing coupling part position are concentric structure.
Described interior full skirt is back taper full skirt, and the small end conicity of described interior full skirt is identical with mould depanning direction, and described full skirt can be designed as 1 or N number of.
The outside of described insulated tension pole is provided with sealing ring, described sealing ring adopts elastic insulating material, fixing seal structure is defined between described sealing ring and pole housing, described insulated tension pole is positioned at the concentric circles center of switch pole, and described insulated tension pole can move back and forth along concentric circles axis and realize the operation of switch.
Described current transformer inner circle and pole line-outgoing arm all adopt identical has tapered configuration, and described current transformer and pole line-outgoing arm junction are provided with sealing surface, and described sealing surface adopts elastic insulating material.
Described pole line-outgoing arm stretches out outside current transformer, and described current transformer is provided with full skirt, and described full skirt is positioned at the junction of current transformer and pole line-outgoing arm.
Advantage of the present invention is: 1) interior full skirt is adopted inverted cone-shaped structure, interior full skirt can be allowed conveniently stripped when production, increase the inner body of wall of pole along face creepage distance, pole inside is avoided to form condensation, make the effect due to condensation cause the reduction of dielectric strength in pole, realize the generation avoiding switchgear flashover fault.2) insulated tension pole adopts bellow seal structure, can cutoff switch pole and extraneous air exchange, thus avoids the impact of environmental factor switching devices inside.3) current transformer and pole line-outgoing arm adopt tapered configuration, the immersion of steam can be prevented, cause the corrosion of pole switch and the decline of insulating capacity, can also the internal stress that causes of absorbing environmental variations in temperature, avoid internal stress to cause the damage of product structure.
