There is the advantages of small, light-weight, not have to maintenance suitable for frequent operation, arc extinguishing, using more universal in power distribution network.Vacuum
Breaker is 3~10kV, the indoor distribution in 50Hz three-phase alternating current systems, in industrial and mining enterprises, power plant, substation
Protection and control as electrical equipment are used, especially suitable for requiring the field of employment of non-oil ultra high vacuum system, few maintenance and frequent operation,
Breaker is configurable in middle-placed switch cabinet, double-layer cabinet, fixed cabinet and is used as control and protection high voltage electric equipment.Vacuum circuit breaker exists
Because its frequent break-make works during use, often there is situations such as fever thermal-arrest, and then affect its working efficiency, also influence
Its service life.Currently, vacuum circuit breaker majority opens up ventilation opening in its shell, radiate, although there is certain cooling
Effect.But this radiating efficiency is low, the heat of concentration distributes slowly, vacuum circuit breaker operation failure often occurs, is influencing it just
It is often used, also affects its service life.
Invention content
The utility model main purpose is to solve the above deficiency, provides a kind of radiating efficiency height, avoids vacuum circuit breaker
Generate heat thermal-arrest, ensures the novel vacuum circuit breaker of vacuum circuit breaker service life.
A kind of novel vacuum circuit breaker, including shell, contact, pole, vacuum interrupter, temperature sensor, blast pipe, spray
Head, thermovent, solenoid valve, connecting tube, compressed air pump, controller, insulated tension pole and spring operating mechanism, thermovent setting exist
In housing sidewall, pole and spring operating mechanism are arranged in shell, and vacuum interrupter and insulated tension pole are arranged in pole
Portion, insulated tension pole are connect with vacuum interrupter, and contact is arranged in the upper housing, and contact is connect with pole, temperature sensor setting
In shell internal upper part, blast pipe is arranged in shell and is located at pole side, and nozzle is arranged on blast pipe and opposite pole, pressure
Contracting air pump is arranged in shell lower part, connecting tube one end and connect the other end with compressed air pump and connect with blast pipe, solenoid valve
It is arranged on blast pipe, controller is arranged in shell, and temperature sensor, solenoid valve and compressed air pump pass through cable and control
Device connects.
Further, the blast pipe quantity of the novel vacuum circuit breaker is 5 to 12.
Further, the temperature sensor quantity of the novel vacuum circuit breaker is 3 to 5.
Compared with the existing technology, the advantageous effects of the utility model acquirement are：Novel vacuum circuit breaker heat dissipation effect
Fruit is good, and effectively vacuum circuit breaker internal heat generation thermal-arrest can shed, preferably ensured vacuum circuit breaker normal work, it is ensured that
Vacuum circuit breaker quality ensure that vacuum circuit breaker service life.

Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining practical new
Type is not intended to limit the scope of the utility model.
A kind of novel vacuum circuit breaker, including shell 1, contact 2, pole 3, vacuum interrupter 4, temperature sensor 5, spray wind
Pipe 6, nozzle 7, thermovent 8, solenoid valve 9, connecting tube 10, compressed air pump 11, controller 12, insulated tension pole 13 and spring operation
Mechanism 14, thermovent 8 are arranged on 1 side wall of shell, and pole 3 and spring operating mechanism 14 are arranged in shell 1, vacuum interrupter
4 and insulated tension pole 13 be arranged in the inside of pole 3, insulated tension pole 13 is connect with vacuum interrupter 4, contact 2 be arranged on shell 1
Portion, contact 2 are connect with pole 3, and for the setting of temperature sensor 5 in 1 internal upper part of shell, the setting of blast pipe 6 is in shell 1 and is located at pole
3 side of column, nozzle 7 are arranged on blast pipe 6 and against poles 3, and lower part, connecting tube is arranged in shell 1 in compressed air pump 11
10 one end connect the other end with compressed air pump 11 and are connect with blast pipe 6, and solenoid valve 9 is arranged on blast pipe 6, and controller 12 is set
It sets in shell 1, temperature sensor 5, solenoid valve 9 and compressed air pump 11 are connect by cable with controller 12.
To keep cooling-down effect more preferable, it is ensured that vacuum circuit breaker normal use.6 quantity of blast pipe of the novel vacuum circuit breaker
It is 5 to 12.
To keep monitoring temperature more accurate, accurate cooling-down effect is reached.The temperature sensor 5 of the novel vacuum circuit breaker counts
Amount is 3 to 5.
