Description

A kind of SF with high in the clouds monitoring6Breaker prevents liquefying plant

Technical field

The utility model is related to a kind of SF with high in the clouds monitoring₆Breaker prevents liquefying plant.

Background technology

SF₆（Sulfur hexafluoride）It is a kind of colourless, tasteless, nontoxic, stable chemical performance, do not fire, is in gaseous at normal temperatures Material, with the good characteristic of heat conduction, arc extinguishing, insulation effect, is taken as arc-extinguishing medium in insulation in 10-500KV breaker Obtained and be widely popularized and apply.SF₆Breaker has good break performance, without maintenance and easy to use, safely may be used Lean on, be widely used in operation of power networks.In recent years, grid equipment was newly regenerated comparatively fast, and armamentarium performance is significantly improved, 110KV and above breaker almost all are replaced by SF₆Equipment, greatly improves the reliability and stability of operation of power networks.

But some cold districts in China, winter outdoor ambient temperature reach 40 DEG C, some areas even reach To 50 DEG C.SF₆Gas produces condensation, liquefaction under ultra-low temperature surroundings, causes SF₆Gas pressure and density decline, and then seriously Impact is with SF₆Gas is dielectric and arc extinguishing normal operation of circuit breaker, SF₆Gas liquefaction causes circuit breaker lock action Event occurs, and forces SF₆Breaker is out of service, causes large-area power-cuts, and the safety for having a strong impact on converting equipment and electrical network is steady Fixed operation.

Utility model content

Main purpose of the present utility model is to provide a kind of SF with high in the clouds monitoring₆Breaker prevents liquefying plant, uses To solve the above problems, SF is prevented₆Liquefy at a temperature of setting, it is ensured that normal operation of circuit breaker.

For reaching object above, the technical solution adopted in the utility model is：A kind of SF with high in the clouds monitoring₆Breaker is prevented Only liquefying plant, including gas bomb, copper pipe, heater；Heater be arranged on gas bomb in order to carrying out to gas bomb plus Heat；Gas bomb is by copper pipe and SF₆The air chamber of breaker is connected.

Further, the described liquefying plant that prevents also is included for detecting SF in gas bomb₆The relay of density.

Further, described heater includes electrically insulating silicone rubber heating plate, A.C. contactor, temperature controller and communication Box；Described electrically insulating silicone rubber heating plate is in order to SF₆Heated；Described A.C. contactor is whole in order to open or close Individual heater circuit；Temperature controller has temperature sensor in order to detect SF₆Temperature while temperature controller can be according to the change of temperature Make corresponding control；Communication box can be sent to cloud server Current Temperatures, heated condition, electricity consumption situation, and high in the clouds takes Business device can be sent to user mobile phone or computer related data.

Further, described heater also includes protective cover, installed in the periphery of the anti-heater.

Further, described communication box can be by the SF in gas bomb₆It is sent to cloud server.

The beneficial effects of the utility model：The device can be automatically controlled, and can effectively prevent SF₆Liquefy；Using Communication box, user can check each item data of the device in real time by mobile phone or computer, convenient for users.

Description of the drawings

Fig. 1 is the connection figure of one preferred embodiment of the utility model；

Fig. 2 is the fundamental diagram of heater of the present utility model.

Specific embodiment

Hereinafter describe for disclosing the utility model so that those skilled in the art can realize the utility model.Hereinafter retouch Preferred embodiment in stating is only used as citing, it may occur to persons skilled in the art that other obvious modifications.

As shown in figure 1, a kind of SF with high in the clouds monitoring₆Breaker prevents liquefying plant, including gas bomb 3, copper pipe 4, adds Thermal 2；Heater 2 is arranged in order to heat to gas bomb 3 on gas bomb 3；Gas bomb 3 is by copper pipe 4 and SF₆Disconnected The air chamber 5 of road device is connected, on the one hand can be by the SF of the heating in gas bomb 3₆Gas is swapped with the gas in air chamber 5, On the other hand the heat of gas bomb can also be delivered to further to the SF in air chamber 5 in air chamber 5 by copper pipe 4₆Gas is carried out Heating.

Further, the described liquefying plant that prevents also is included for detecting SF in gas bomb 3₆The relay 1 of density.

Further, as shown in Fig. 2 described heater 2 includes electrically insulating silicone rubber heating plate 21, A.C. contactor 22nd, temperature controller 23, protective cover and communication box 24, described electrically insulating silicone rubber heating plate 21 is in order to SF₆Heated, described , in order to open or close whole heater circuit, temperature controller 23 is with temperature sensor 231 in order to detect SF for A.C. contactor 22₆ Temperature while temperature controller 23 can make corresponding control according to the change of temperature, protective cover is arranged on the outer of heater 2 Week is in order to the equipment of protecting other internal, and communication box 24 can be sent to cloud Current Temperatures, heated condition, electricity consumption situation End server, can be sent to user mobile phone or computer to be checked related data by cloud server.

As shown in Fig. 2 the operation principle of heater 2 is as follows：The minimum of a temperature is set by temperature controller 23, when Temperature sensor 231 detects SF₆Temperature less than setting value when, the closure of A.C. contactor 22 is made whole heating by temperature controller 23 Circuit is in the conduction state, and electrically insulating silicone rubber heating plate 21 starts to SF₆Heating；When temperature sensor 231 detects SF₆Temperature When degree is higher than setting value, A.C. contactor 22 is disconnected and then disconnects whole circuit by temperature controller 23, electrically insulating silicone rubber heating plate 21 stop heating.

Also, the circuit in heater 2 adopts 220V voltage, power is 200W.

General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply principle of the present utility model, the utility model also has respectively on the premise of without departing from the utility model spirit and scope Changes and improvements are planted, these changes and improvements are both fallen within the range of claimed the utility model.The utility model is required Protection domain defined by appending claims and its equivalent.
