Background technology
Along with the continuous superhigh pressureization of China's power transmission and transformation in modern age voltage, more and more high requirement has been proposed for power transformer, instrument transformer, electrical equipment, electronic devices and components reliability of operation and working life in abominable, high load capacity environment.Therefore exploring and develop new insulating material, insulation system and technology is one of important measures of satisfying above-mentioned requirements.
In the existing high voltage switchgear, except that comprising outside the Pass the vacuum load switch, also the earthed switch that is attached thereto will be housed, therefore the separate installation of on-load switch and earthed switch in the high voltage switchgear needs the safe distance that keeps certain.Simultaneously also to keep certain safe distance between the load bus (exposed copper bus) of phase and phase in the high voltage switchgear because the dielectric between them is an air, with 12 kilovolts be example, its safe distance at least will be more than 125 millimeters; Therefore, the size of on-load switch equipment is still bigger, floor space is relatively also big, need the switchgear of assembling by this way, the level of its high voltage load switch and earthed switch and connection bus mutually insulated, can be affected with condition such as airborne humidity, dust and insect, have the potential safety hazard of short circuit, and need often to safeguard.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, volume is little, the insulating protection ability is strong two vacuum bubbles arc control device devices to use dangerous, problem such as easy care not to solve switchgear of the prior art.
The technical solution of the utility model is achieved in that on-load switch and two kinds of vacuum interrupter switches of earthed switch is encapsulated in the pole unit of poured with epoxy resin admittedly.Vacuum interrupter one end is a fixed contact, and the on-load switch fixed contact is used for outlet, promptly connects load, and the fixed contact of earthed switch is used for ground connection; The other end is a moving contact, the moving contact of two vacuum interrupters is for being connected in parallel, be connected with inlet wire side novel combination type connection bus in the high voltage switchgear, described novel combination type connection bus is sealed epoxy resin bushing, and is connected as a single entity with the together solid envelope in pole unit.
The beneficial effects of the utility model are:
Of the present utility model pair the vacuum bubbles quenching pot is simple in structure, volume is little, environmental protection, insulating protection ability are strong; Be not affected, eliminated the potential safety hazard of short circuit between the switch, the reliability height with condition variations such as airborne humidity, dust and insect; Simultaneously, with solid Feng Chengyi the pole unit of two vacuum interrupters, realized the non-maintaining of high voltage load switch and earthed switch with epoxy resin.
