Abstract
The utility model relates to an isothermal testing density relay which is used to monitor the density of gaseous sulfur hexafluoride of a high-voltage switch and consists of a gas storage chamber, a standard gas chamber, a gas storage chamber inlet connector, a gas storage chamber outlet connector, a testing connector I, a shell, a microswitch, a testing connector II and a retainer. The standard gas chamber is arranged in the gas storage chamber and is supported in the inner cavity of the gas storage chamber through the retainer. The gas storage chamber inlet connector is arranged on the gas storage chamber and is connected with the gas chamber of the switch equipment. The gas storage chamber outlet connector is arranged on the gas storage chamber and is connected with the testing connector I which is connected with the shell, and the testing connector II connected with the standard gas chamber is arranged on the shell. Since the standard gas chamber is arranged in the gas of the working equipment, temperature difference can be avoided and the detection precision can be improved. The gas storage chamber is of the structure of a heat insulating layer, so errors caused by the influence of the surrounding temperature can be avoided.
Description
Technical field
The utility model relates to a kind of density monitor that the sulfur hexafluoride gas density of high-voltage switch gear is monitored, specifically a kind of relay for isothermally testing density.
Background technology
Relevant by retrieval patent documentation does not retrieve the relay for isothermally testing density identical with the utility model structure at present as yet.The density monitor that existing power industry is monitored the sulfur hexafluoride gas that uses in the high-voltage switch gear generally adopts bellows to combine with sensitive switch gas is monitored, because high-voltage switch gear is operation out of doors generally, continuous variation along with weather environment, temperature also will change thereupon, cause the gas pressure in the equipment to change, particularly under the higher environment of variations in temperature, variation of temperature often makes density monitor generation false alarm easily.The relay with adjustment compensation that uses is at present generally realized Temperature Compensation by manual adjustments and adjustment spring, but also regulate and exist error equally owing to the scope of its compensation and by the adjustment spring, make the running quality of equipment be difficult to be guaranteed, so be necessary existing density monitor is improved, to improve the utilization and operation quality of equipment better.
Summary of the invention
The purpose of this utility model is that a kind of improvement on existing density monitor basis will be provided, and has the isothermal test, and relay for isothermally testing density simple in structure.
In order to realize the purpose of this utility model, the utility model by the following technical solutions:
Relay for isothermally testing density, form by air storage chamber, standard air chamber, air storage chamber inlet suction port, air storage chamber air outlet adapter, test splice I, housing, sensitive switch, test joint II, retainer, be provided with the standard air chamber in air storage chamber, described standard air chamber is bearing in the inner chamber of air storage chamber by retainer; Be provided with the air storage chamber inlet suction port on air storage chamber, described air storage chamber inlet suction port is connected with the air cavity of switchgear; Be provided with the air storage chamber air outlet adapter on air storage chamber, described air storage chamber air outlet adapter is connected with test splice I; Test splice I is connected with housing; In the inner chamber of housing, be provided with sensitive switch, on housing, be provided with the test joint II that links to each other with the standard air chamber; Described sensitive switch is connected with the alarm relay device.
Described air storage chamber is the airtight air container of an insulation, and by internal layer, heat-insulation layer, the outer composition, heat-insulation layer is arranged between internal layer and the skin.
During use, relay for isothermally testing density of the present utility model is installed in the inside of mechanism case, and the air storage chamber inlet suction port is connected with the sulfur hexafluoride gas joint of the high voltage switchgear of operation by tube connector; Open the valve of the sulfur hexafluoride gas joint of high voltage switchgear, the sulfur hexafluoride gas in the operational outfit enters by tube connector in the inner chamber of air storage chamber, and the standard air chamber of making is in the gas of operational outfit, and is in same temperature state; Gas in the operational outfit promotes sensitive switch by test splice I, and compares with the gas of standard air chamber, carries out the gas density in the checkout equipment; The standard air chamber is arranged in the airtight air storage chamber, its objective is in order to make temperature in the air storage chamber and standard air chamber temp effect such as reach to be provided with.Air storage chamber is designed to have the version of heat-insulation layer, its objective is for fear of residing position of relay and working equipment to have temperature difference setting.
The utility model has the advantages that: because the standard air chamber is arranged in the environment of working equipment gas, makes standard air chamber and equipment gas be in same temperature, thereby avoided the temperature difference between standard air chamber and the working equipment, accuracy of detection is significantly improved; Because air storage chamber is the version with heat-insulation layer, thereby the error of having avoided ambient temperature effect to bring; Because rational in infrastructure, simple, the measuring accuracy height has been avoided the generation of false alarm greatly, so very big practical value is arranged.
