Description
technical field:
The utility model relates to a kind of installation instrument of power transformation engineering, particularly relates to a kind of sulfur hexafluoride gas cylinder heating device.
background technique:
Sulfur hexafluoride gas plays insulation in GIS equipment, and GIS equipment, in running, keeps certain SF-
6gas pressure, just can ensure enough insulating strengths, thereby ensures the safe and stable operation of GIS equipment.But, because GIS equipment can not be accomplished absolutely to seal, so long playing GIS equipment is bound to occur the situation that GIS air pressure is inadequate, at this time just need to carry out SF-to GIS equipment
6tonifying Qi.Traditional supplementing method for air generally adopts sulfur hexafluoride gas cylinder, supplements by reduction valve.But there is following two problems (1) SF-in tonifying Qi body process like this
6in gas cylinder, be liquid, become gas, SF-after being filled with GIS air chamber by reduction valve
6gasification, can absorb a large amount of heat, may cause valve frosting, causes aeration speed slow.(2) along with the minimizing of tolerance in gas cylinder, the reduction of gas temperature, causes air pressure to reduce, and makes SF-
6gas cannot be fully used, and causes SF-
6gas waste.
model utility content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to use, temperature control accurately and improve the sulfur hexafluoride gas cylinder heating device of gas effciency.
The technical solution of the utility model is: a kind of sulfur hexafluoride gas cylinder heating device, containing having heaters, controller and temperature indicator, described heater is arranged in insulation coating and is connected with outside controller, described insulation coating is pressed close on the surface of sulfur hexafluoride gas cylinder to be provided with temperature transducer, described temperature transducer is connected with described controller, and described heater is connected with power supply by plug; Described heater is tortuous surrounding type resistance wire or heat tape; Described temperature transducer is thermistor; Described insulation coating is nonwoven layer or felt layers; Described controller is PID controller, and is provided with overcurrent protector.
Described controller is connected with duct thermostat and temperature indicator.
The beneficial effects of the utility model are:
1, the utility model has reduced SF-greatly
6the time that tonifying Qi spends, thus maintainer's working efficiency on original basis, farthest reduced.
2, the utility model integrates heating, power control, temperature control protective function, by automatic control, to gas cylinder heating, improves SF-
6gas cylinder residual gas pressure, improves gas utilization ratio.
3, the utility model uses PID controller, realizes the thermostatically control to setting temperature, utilizes voltage-regulation to heat gas cylinder, and with overcurrent protection function, shows in real time gas cylinder temperature by thermistor.
4, the utility model is simple in structure, easy to use, temperature control accurate and improve gas effciency, and it is applied widely, is easy to promote, and has good economic benefit.
brief description of the drawings:
Fig. 1 is the structural representation of sulfur hexafluoride gas cylinder heating device;
Fig. 2 is the circuit theory diagrams of sulfur hexafluoride gas cylinder heating device shown in Fig. 1.
embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, in figure, 1-is incubated coating, 2-controller, 3-plug.
Sulfur hexafluoride gas cylinder heating device is containing having heaters, controller 2 and temperature indicator, wherein: heater is arranged in insulation coating 1 and is connected with outside controller 2, being incubated coating 1 presses close on the surface of sulfur hexafluoride gas cylinder to be provided with temperature transducer (not shown in FIG.), temperature transducer is connected with controller 2, and heater is connected with power supply by plug 3.
Heater is tortuous surrounding type resistance wire or heat tape; Temperature transducer is thermistor.Controller 2 is connected with duct thermostat and temperature indicator.Insulation coating 1 is nonwoven layer or felt layers; Controller 2 is PID controller, and is provided with overcurrent protector.
When use, with being incubated coating 1, sulfur hexafluoride gas cylinder is rolled, then plug 3 is connected with power supply, open controller 2, be set to the temperature needing, controller 2 will use pid algorithm to control output automatically, thereby controls the temperature of sulfur hexafluoride gas cylinder.After tonifying Qi completes, plug 3 is pulled out and extracts insulation coating 1.
Claims (2)
1. a sulfur hexafluoride gas cylinder heating device, containing having heaters, controller and temperature indicator, it is characterized in that: described heater is arranged in insulation coating and is connected with outside controller, described insulation coating is pressed close on the surface of sulfur hexafluoride gas cylinder to be provided with temperature transducer, described temperature transducer is connected with described controller, and described heater is connected with power supply by plug; Described heater is tortuous surrounding type resistance wire or heat tape; Described temperature transducer is thermistor; Described insulation coating is nonwoven layer or felt layers; Described controller is PID controller, and is provided with overcurrent protector.
