Abstract
The utility model discloses a gas insulation metal enclosed switch device, which comprises a circuit breaker main cylinder body, wherein a heating band is wound on the outer wall of the circuit breaker main cylinder body, and the heating band is connected with a temperature controller used for controlling the operation of the heating band according to external environment temperature variation of a circuit breaker. The gas insulation metal enclosed switch device, that is to say a GIS circuit breaker, can be used in low temperature environment, the heating band is wound on the circuit breaker main cylinder body, and the heating band heats the circuit breaker main cylinder body so as to improve the temperature of sulfur hexafluoride gas in the main cylinder body, thus the sulfur hexafluoride gas in the main cylinder body is prevented from liquefaction, which influences the normal operation of the circuit breaker, and the heating band is connected with the temperature controller, thus when external environment temperature is lower than a set temperature, the heating band automatically carries out uniform heating to the sulfur hexafluoride gas in the circuit breaker main cylinder body, the sulfur hexafluoride gas in the circuit breaker is prevented from liquefaction, and the requirement of normal operation of the circuit breaker in low temperature environment can be satisfied.
Description
Technical field
It is GIS that the utility model relates to a kind of Cubicle Gas-Insulated Switchgear, particularly a kind of low temperature GIS circuit breaker that is applied to ambient temperature still can safe operation in the time of subzero 40 ℃～subzero 50 ℃.
Background technology
GIS is a Cubicle Gas-Insulated Switchgear; It comprises equipment such as circuit breaker, isolating switch, earthed switch; Wherein circuit breaker comprises the main cylinder that is filled with sulfur hexafluoride gas, and setting operation cabinet below main cylinder is provided with the isolating switch cylindrical shell above main cylinder; The sulfur hexafluoride gas that fills in the main cylinder guarantees the operate as normal of circuit breaker as insulation and arc-extinguishing medium; But the useful performance of sulphur hexafluoride realizes that under certain density and pressure effect when temperature drops to a certain degree, liquefaction phenomenon will appear in the inner sulfur hexafluoride gas of circuit breaker.Because sulfur hexafluoride gas liquefies under low temperature environment, the insulation of the sulfur hexafluoride gas after the liquefaction and arc extinguishing ability are lost basically, cause the circuit breaker can't operate as normal, bring influence to the work under low temperature environment.
The utility model content
The purpose of the utility model is to provide a kind of Cubicle Gas-Insulated Switchgear, to solve the technical problem that the circuit breaker that is filled with sulfur hexafluoride gas in the prior art under the low temperature environment can't operate as normal.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of Cubicle Gas-Insulated Switchgear; Comprise the circuit breaker main cylinder; It is characterized in that: be wound with the heating tape on the outer tube wall of described circuit breaker main cylinder, described heating tape is connected with according to the circuit breaker ambient temperature and changes the thermostat of controlling heating tape work.
Heating tape on the main cylinder of described circuit breaker is furnished with two places on the main cylinder bearing of trend.
The below of described circuit breaker main cylinder is provided with the manipulation cabinet, handles in the cabinet and is furnished with a plurality of plate electric heaters.
The madial wall of described manipulation cabinet is provided with warming plate.
The beneficial effect of the utility model is: the Cubicle Gas-Insulated Switchgear that the utility model provided is that the circuit breaker of GIS can be applicable under the low temperature environment; On the main cylinder of circuit breaker, twine the heating tape; By the heating tape circuit breaker main cylinder is heated to improve the temperature of the inner sulfur hexafluoride gas of main cylinder; Avoid sulfur hexafluoride gas in the main cylinder liquefaction to occur and influence the operate as normal of circuit breaker, and because the heating tape links to each other with thermostat, control the heating tape according to the variation of the ambient temperature of circuit breaker and work; When external environment condition is reduced to design temperature and when following; Evenly heating is carried out automatically to the inner sulfur hexafluoride gas of circuit breaker main cylinder in the heating tape, guarantees that the inner sulfur hexafluoride gas of circuit breaker does not liquefy, and satisfies the operate as normal needs of circuit breaker under low temperature environment.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the vertical view that removes among Fig. 1 behind the main cylinder.
Embodiment
Like Fig. 1, shown in Figure 2; A kind of Cubicle Gas-Insulated Switchgear; Comprise circuit breaker main cylinder 2; Below main cylinder 2, be provided with and handle cabinet 1, be wound with on the main cylinder 2 upper edge main cylinder bearing of trends in the heating tape, 3, two place, heating tape, two places 3 a wherein place circuit breaker near the outer tube wall of handling cabinet on, another place pulls out on the outer tube wall between the mouth in two outlets of circuit breaker; Heating tape in the present embodiment has attemperator; Described heating tape is made up of silicon rubber heater, insulation material and stainless steel casing, and wherein silicon rubber heater is processed by insulating material parcel nickel filament, and the heating tape 3 on the main cylinder 2 is connected with the thermostat of controlling heating tape work according to the variations in temperature of the external environment condition of circuit breaker; When the ambient temperature of circuit breaker is reduced to the design temperature of temperature control and when following; Thermostat will be controlled heating tape work the sulfur hexafluoride gas in the circuit breaker main cylinder will be carried out automatic uniform heating, and rise when reaching established standards when the temperature of the sulfur hexafluoride gas of barrel, and thermostat will control the heating tape and quit work with reduction consumption; Thereby make the inner sulfur hexafluoride gas all-the-time stable of main cylinder in the temperature range that allows; In handling cabinet 1, be furnished with a plurality of heaters, the heater here is a plate electric heater 4, on the madial wall of handling cabinet inside, is furnished with warming plate 5.
In the present embodiment through heating tape 3 is set on main cylinder 2; And in manipulation cabinet 1, warming plate 5 and plate electric heater 4 are set; Thereby can be so that the sulfur hexafluoride gas in the main cylinder of circuit breaker 2 be subzero 40 ℃～subzero 50 ℃ liquefying, circuit breaker can operate as normal.
GIS also comprises standard components such as isolating switch, earthed switch and sleeve pipe except circuit breaker; General sulfur hexafluoride gas liquefaction pressure corresponding in the time of subzero 40 ℃ is 0.365MPa; Can satisfy the operate as normal of GIS through the specified gas pressure that reduces standard components such as isolating switch, earthed switch and sleeve pipe so at low temperature environment; Rated pressure like standard components such as isolating switch, earthed switch and sleeve pipes is that 0.4 MPa, alarm pressure are 0.35 MPa, minimal function pressure position 0.33 MPa, to guarantee the operate as normal of GIS under subzero 50 ℃～subzero 40 ℃ environment.
And for extremely low temperature out of doors such as subzero 50 ℃ of sleeve pipes of operation down; The support cylindrical shells of revising under the sleeve pipe that adopt more; Increase the contact area that can be used for heating on the cylindrical shell; On cylindrical shell, lay the heating tape then to realize heating, guarantee that sulfur hexafluoride gas does not liquefy under low temperature environment the inside pipe casing air chamber.
