Abstract

The invention relates to a temperature control inflating device for sulfur hexafluoride, wherein the device inflates and re-inflates high-voltage electric equipment and has a temperature control function. The device consists of an inlet joint valve, a heating device, a vacuum pressure controller, a temperature control device, a temperature control probe, a temperature control valve, an outlet joint valve and the like. The heating device consists of a heater, an inner tube and the like. As the temperature control device is adopted, the heater pre-heats and warms to prevent SF6 is prevented from being condensed in an inflating pipeline when the heater performs preheating and heating in winter; and the situation that high-density gas which is not completely vaporized is inflated in summer is avoided, so that normal operation of the high-voltage electrical equipment is ensured. As the vacuum pressure controller is arranged, deflation and inflation are possible and the purity of SF6 inflated is improved during inflation. As the temperature control valve is arranged, the temperature of SF6 inflated is consistent to the environmental temperature. The device is compact in structure, simple and safe to operate and reliable in performance, so that the device has huge practical and promotional values.

Description

A kind of sulphur hexafluoride temperature-control inflation device
Technical field
The present invention relates to a kind of device that high voltage electric equipment is safeguarded, specifically a kind of to high voltage electric equipment inflate, a kind of sulphur hexafluoride temperature-control inflation device of tonifying Qi.
Background technique
Through retrieving relevant patent documentation, not yet retrieve identical with the structure of the present invention a kind of sulphur hexafluoride temperature-control inflation device that high voltage electric equipment is carried out sulfur hexafluoride gas-filled, tonifying Qi of being used at present.Have now high voltage electric equipment is carried out sulfur hexafluoride gas-filled, tonifying Qi, general adopt with the sulphur hexafluoride gas cartridge by trachea directly to high voltage electric equipment inflate, tonifying Qi, because SF6 gas is very easily liquefaction under low temperature, high pressure, in SF6 gas decompression process, a large amount of heat around needing to absorb, thereby, be easy to condensation in the gas ducting, especially in winter, be difficult to from the SF6 steel cylinder, fill gas; In summer, this simple method is directly to the high voltage electric equipment gas injection, vaporization, highdensity SF6 gas do not pour fully owing to have, so that high voltage electric equipment is after operation a period of time, the rising of high voltage electric equipment air pressure inside, air pressure wild effect occur, have a strong impact on high voltage electric equipment and normally move.
Summary of the invention
The objective of the invention is to provide a kind of temp. control function that has, can adapt to a kind of sulphur hexafluoride temperature-control inflation device that various ambient temperatures are reliably inflated high voltage electric equipment.
Technical characteristics of the present invention is: considering that high voltage electric equipment is filled with the sulfur hexafluoride gas consistent with the site environment temperature, and be designed to a kind of sulphur hexafluoride temperature-control inflation device of being comprised of air inlet connecting head valve, tracheae I, heating equipment, vacuum pressure controller, temperature controlling device, temperature probe, thermostat valve, tracheae II, air outlet adapter valve and tracheae III on the basis simple to operate, safe and reliable, heating equipment is connected with the air inlet connecting head valve through the tracheae I; Temperature controlling device is connected with heating equipment; Temperature probe is connected on the tracheae III and is connected with temperature controlling device; Vacuum pressure controller is connected with the air outlet adapter valve through the tracheae II; Thermostat valve is connected with tracheae II, tracheae III, and is connected with temperature controlling device.
Described heating equipment is comprised of shell, heater, inner tube, and the heater in the heating equipment is toroidal ring structure.
During use, close the air inlet connecting head valve on the sulphur hexafluoride temperature-control inflation device, the air outlet adapter valve, vacuum pressure controller connects outside vacuum pumping device, sulphur hexafluoride temperature-control inflation device is vacuumized, after vacuumizing end, the air inlet connecting head valve connects the SF6 gas cartridge, the air outlet adapter valve connects high voltage electric equipment, open the air outlet adapter valve, connect temperature controlling device, the heater preheating, heat, when temperature controlling device shows suitable temperature, then open the air inlet connecting head valve, the not fully vaporization of going out in the SF6 steel cylinder, high density SF6 gas is through preheating, reach suitable temperature and fully vaporization behind the abundant absorbing heat of heater inner tube of heating, temperature controlling device is opened thermostat valve, by the air outlet adapter valve sulphur hexafluoride is filled with high voltage electric equipment.
Advantage of the present invention is: owing to adopted temperature controlling device, by heater the SF6 gas that will be filled with is carried out preheating, heats, SF6 gas is in decompression process, fully absorbed the vaporize amount of heat of required absorption of SF6 gas, thereby in gas ducting, stopped the condensation phenomenon, especially out of doors in winter, can from the SF6 steel cylinder high voltage electric equipment be filled with and the suitable SF6 gas of outdoor environment temperature very smoothly; Owing to adopted temperature controlling device, carry out preheating by heater to being filled with SF6 gas, heat, in summer, eliminate straightforward procedure and directly high voltage electric equipment has been poured not fully vaporization from the SF6 steel cylinder, the phenomenon of high density SF6 gas, the high voltage electric equipment internal air pressure of guaranteeing working state under high voltage electric equipment internal air pressure and the normal temperature when just inflation finishes is consistent, having stopped because of straightforward procedure the air pressure inside after high voltage electric equipment moves a period of time that directly inflation causes to high voltage electric equipment raises, the air pressure wild effect is guaranteed the normal operation of high voltage electric equipment; Owing to be provided with vacuum pressure controller, can vacuumize high voltage electric equipment, exit, inflate, when inflation, sulphur hexafluoride temperature-control inflation device is vacuumized, eliminate air and the contained humidity thereof when simply pipeline is directly inflated high voltage electric equipment brought into, improved the purity that is filled with SF6 gas; Owing to be provided with thermostat valve, thereby guaranteed that the sulfur hexafluoride gas temperature that is filled with is consistent with ambient temperature; Because compact structure, simple to operate, safety, reliable performance are so there is very large practical and popularizing value.
