Abstract
The utility model relates to a novel embedded pole vacuum circuit breaker. The novel embedded pole vacuum circuit breaker comprises a vacuum arc-extinguishing chamber (1), an upper contact arm (2) and a lower contact arm (3), and is characterized in that the vacuum arc-extinguishing chamber (1) and the upper contact arm (2) are immobilized together. According to the novel embedded pole vacuum circuit breaker provided by the utility model, a high-performance epoxy resin material is adopted, and an automatic pressure gel process (APG) is adopted for immobilizing the vacuum arc-extinguishing chamber, the upper contact arm and the lower contact arm together, so that the novel embedded pole vacuum circuit breaker is suitable for working environments of large sand storm, dryness, alpine plateau, humidity, dirt, underground and power stations, and can simultaneously reduce the oxidation of a conductive part of the circuit breaker, reduce the resistance of a loop and improve the reliability in connection of a main loop; and tests prove that the mechanical service life can achieve 30000 times.
Description
Technical field
The utility model relates to a kind of Novel solid sealing post vacuum circuit-breaker.
Background technology
At present, high-pressure vacuum breaker is widely used in the power transmission and distribution switchgear assembly, and its vacuum vacuum interrupter is generally selected sleeve assembling form, is subject to the environment limitations such as filth, moisture, dust storm, has reduced the electric property of product, and useful life is short.
The utility model content
The purpose of this utility model provides a kind of Novel solid sealing post vacuum circuit-breaker, can use under abominable operational environment, and improve the reliability that major loop connects.
A kind of Novel solid sealing post vacuum circuit-breaker comprises vacuum interrupter, upper contact arm and lower contact arm, and its special feature is: described vacuum interrupter is enclosed in admittedly with upper contact arm.
Wherein vacuum interrupter also is enclosed in admittedly with lower contact arm.
Wherein solid envelope adopts epoxide resin material.
The utility model provides a kind of Novel solid sealing post vacuum circuit-breaker, adopt the high-performance epoxy resin material, by automatic pressure gelation process (APG), reaching the vacuum vacuum interrupter up and down, contact arm is enclosed in together admittedly, be applicable to that dust storm is large, the operational environment in drying, highland and severe cold, moisture, filth, down-hole and power station, reduced again simultaneously the oxidation of the conducting position of circuit breaker, reduced loop resistance, improved the reliability that major loop connects, through evidence, can reach mechanical endurance 30000 times.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of Novel solid sealing post vacuum circuit-breaker, comprise vacuum interrupter 1, upper contact arm 2 and lower contact arm 3, described vacuum interrupter 1 is enclosed in admittedly with upper contact arm 2, lower contact arm 3 respectively, Gu envelope specifically adopts epoxide resin material, form by automatic pressure gelation process (APG) cast.
The utility model is that vacuum interrupter 1 is enclosed in by Epoxy Resin with upper contact arm 2, lower contact arm 3; both reduced the oxidation of circuit breaker conducting position; reduced loop resistance; improve again the reliability that major loop connects, provide more fully mechanical protection for vacuum interrupter 1 after the solid envelope cast of simultaneously employing.
Claims (3)
1. a Novel solid sealing post vacuum circuit-breaker comprises vacuum interrupter (1), upper contact arm (2) and lower contact arm (3), and it is characterized in that: described vacuum interrupter (1) is enclosed in admittedly with upper contact arm (2).
2. a kind of Novel solid sealing post vacuum circuit-breaker as claimed in claim 1, it is characterized in that: wherein vacuum interrupter (1) also is enclosed in admittedly with lower contact arm (3).
3. a kind of Novel solid sealing post vacuum circuit-breaker as claimed in claim 1 or 2 is characterized in that: wherein admittedly seal and adopt epoxide resin material.
