Abstract
The utility model discloses a transformer pressure release valve tester. The tester solves the problem that the quality of pressure release valves cannot be effectively tested at present, and at leasthas the following advantages: the structure is simple, use is convenient, and the tester can effectively test whether the action of a pressure release valve is accurate, so that a transformer can continuously, safely and stably operate. The structure of the tester is as follows: the tester comprises a sealed case body, the side of the case body is provided with a group of positioning screw holesfor mounting the pressure release valve, the case body is provided with at least one compressed air inlet, a pressure meter is mounted on the case body through a pressure meter-mounting hole, and thecase body is also provided with a reinforcer.
Description
Technical field
The utility model relates to a kind of transformer pressure relief valve verifying attachment.
Background technology
Along with going deep into of the city net and the upgrading of rural power grids, the power consumption in city and rural area has all had significantly to be increased, but because the maintenance of part low-voltage circuit is not in place, the possibility that overload and short circuit take place increases greatly, so that the electric current of transformer surpasses several times even tens times of rated current, because the sharp increase of electric current, the coil temperature of substation transformer raises rapidly, cause insulation accelerated aging, forming the fragment shape comes off, make the line body exposed and cause turn-to-turn short circuit, the heat that short circuiting arc or overcurrent produce decomposes transformer oil, produces a large amount of gases at high pressure, makes fuel tank bear huge pressure, may make the fuel tank distortion when serious even break, and with the sprinkling of combustibility oil completely.At this situation, pressure relief valve is installed additional in transformer producer on transformer, when the transformer internal pressure reaches polarization value, and relief valve releases pressure, thus reach the purpose of protecting transformer.But when transformer production, producer can't effectively check pressure relief valve and determine the pressure relief valve quality, can not guarantee the operational reliability of outsourcing pressure relief valve.
Summary of the invention
The purpose of this utility model is exactly in order to solve the problem that the pressure relief valve quality can't effectively detect, provide a kind of have simple in structure, easy to use, whether accurate, the transformer pressure relief valve verifying attachment of advantages such as the continuous safe and stable operation of assurance transformer if can effectively detect its action.
For achieving the above object, the utility model adopts following technical scheme:
A kind of transformer pressure relief valve verifying attachment, it comprises a seal case, described casing side is provided with the positioning screw hole of one group of setting pressure relief valve, on casing, be provided with at least one pressurized air air admission hole, tensimeter is installed on the casing by the tensimeter mounting hole, also is provided with bracing means on casing.
Described bracing means comprises the angle bar that is arranged on casing wall middle part, and a pair of channel-section steel that is arranged on bottom half.
The device of detected pressures relief valve of the present utility model makes it produce pressure by pressurized air, and when reaching the pressure polarization value, whether the inspection pressure relief valve moves.Determine the pressure relief valve precision maneuver, guarantee the continuous safe and stable operation of transformer.
Casing is that hermetically sealed, thickness is that 6 millimeters iron plate is made.1/2 place of every side height installs an angle bar additional, prevents to cause dilatational strain because of applying a large amount of air.Two 550mm channel-section steels are equipped with in the bottom, and floor area is less, is applicable to indoor placement.
During use, install pressure indicator earlier, check whether indicating correct of indicator.Install pressure relief valve to be tested then, no screw is screwed down, in air intake opening, insert special-purpose tracheae.Whether inspection has omission, gas leakage position.Charge into gas during test, observe the gauge hand reading, check whether misoperation of pressure relief valve simultaneously, when indicator points to setting, observe pressure relief valve and whether normally whether move, move.Slowly reduce charging into gaseous tension after inspection finishes, check when reducing to setting whether pressure relief valve resets.After all qualified gas is discharged, pull down the pressure relief valve that has been up to the standards.
The beneficial effects of the utility model are: simple in structure, easy to use, can determine the pressure relief valve precision maneuver, and guarantee the continuous safe and stable operation of transformer.
