Abstract
The utility model discloses a damp-proof device for vacuum circuit breakers and a vacuum circuit breaker with the damp-proof device. The damp-proof device is formed by that a high-plasticity material is embedded in a tight fit mode between the outer wall of the arc extinguishing vacuum tube and the inner wall of the protective sleeve tube of the existing vacuum circuit breaker to form a ring, and high-performance insulating glue is poured towards the ring to form an isolation layer. Thus, the loop of damp on the outer wall of the arc extinguishing vacuum tube is cut off, and consequently, the safety and the reliability of the vacuum circuit breaker is enhanced.
Description
The utility model relates to a kind of outdoor high-voltage switch with arc-control device.
At present, most heavy wool or the sulfur hexafluoride breakers of using of outdoor 10Kv level circuit breaker since they exist separately maintenance numerous and diverse, pollute, have shortcomings such as explosion hazard and inflation difficulty, progressively substituted by vacuum circuit-breaker.Vacuum circuit-breaker is by the arc extinguishing vacuum tube, form into and out of essential parts such as bus terminal, protective casing and casings.End of incoming cables daughter board and leading-out terminal daughter board are connected to the two ends of arc extinguishing vacuum tube.The protective casing that one protection itself and external insulation are arranged outside the arc extinguishing vacuum tube.However, airborne moisture and other impurity (especially in rainy, moist south) still can produce water smoke (claiming condensation again) on arc extinguishing vacuum tube outer wall, when these condensations intensive and when forming the loop, under the breaker open operation state, the circuit breaker two ends be added with high pressure (〉=10Kv), make this loop conducting and cause short circuit accident.
The purpose of this utility model provides a kind of vacuum circuit-breaker that can prevent the device of condensation phenomenon effectively and have aforementioned means.
The anti-condensation device that the utility model relates to is the ring that the insulating material of a high-ductility is made.When practicality, this ring interference fit ground is embedded between the arc extinguishing vacuum tube outer wall and protective casing inwall of existing vacuum circuit-breaker.For guarantee insulation property can be between arc extinguishing vacuum tube outer wall and protective casing inwall on ring casting insulated again glue, form a separator.
The vacuum circuit-breaker with anti-condensation device that the utility model relates to is at the separator that is provided with aforesaid ring on the basis of existing vacuum circuit-breaker between arc extinguishing vacuum tube outer wall and protective casing inwall.
Above-mentioned anti-condensation device and adopt the vacuum circuit-breaker of this device can stop condensation conducting on the arc extinguishing vacuum tube outer wall and the accident that is short-circuited improves the fail safe and the reliability of vacuum circuit-breaker effectively.
Embodiment one, sees accompanying drawing.
End of incoming cables daughter board 1 and leading-out terminal daughter board 2 are connected to the two ends of arc extinguishing vacuum tube 3, are with the protective casing 4 of a protection arc extinguishing vacuum tube 3 and external insulation outside arc extinguishing vacuum tube 3 with one heart.Interference fit ground embeds the insulating material of a high-ductility between arc extinguishing vacuum tube 3 and protective casing 4, as sponge, forms a ring 6.Between arc extinguishing vacuum tube 3 and protective casing 4, form a separator 7 to ring 6 cast High Performance Insulation glue.Ring 6 is divided into the upper and lower two parts that do not leak with separator 7 with arc extinguishing vacuum tube 3, like this, can guarantee that just condensation can not form the loop on arc extinguishing vacuum tube outer wall.
Embodiment two
As previously mentioned, can on arc extinguishing vacuum tube 3 outer walls, establish the separator of the ring more than two at least.
Claims (6)
1, a kind of anti-condensation device that is used for vacuum circuit-breaker is characterized in that: interference fit ground embeds the ring made from the high-ductility material between arc extinguishing vacuum tube outer wall and protective casing inwall.
2, a kind of vacuum circuit-breaker that anti-condensation device is arranged; it is characterized in that: between the inwall of the outer wall of the arc extinguishing vacuum tube of existing vacuum circuit-breaker and protective casing, be provided with the ring made from the high-ductility material; this ring embeds between arc extinguishing vacuum tube outer wall and the protective casing inwall by interference fit, the arc extinguishing vacuum tube is divided into upper and lower two parts of not conducting.
3, according to the described anti-condensation device of claim 1., it is characterized in that: between arc extinguishing vacuum tube outer wall and protective casing inwall, pour into a mould a kind of insulating cement, form a separator to ring.
4, according to the described vacuum circuit-breaker of claim 2., it is characterized in that: between arc extinguishing vacuum tube outer wall and protective casing inwall, pour into a mould a kind of insulating cement, form a separator to ring.
