Abstract
The utility model relates to a portable periodic inspection experimental device of a gas relay, which is composed of a gas pump, batteries, a control circuit, and an electric meter, wherein a gas outlet pipe of the gas pump and two contacts of the control circuit extend outside of a shell body. When the utility model is inspected, the two contacts are respectively connected with a light mash gas contact and a heavy mash gas contact of a relay. By inflating to a gas chamber of the relay or touching a probe of the relay, the number of the electric meter can be observed, so that the operating state of the gas relay can be judged. The utility model has the advantages of simple structure, convenient operation, safety and sanitation in inspection process, and no oil leakage, can finish inspection work by one person, in the whole inspection process, can not damage an oil quality and can improve work quality and work efficiency.
Description
Technical field
The utility model belongs to checkout equipment.
Background technology
Gas relay is the vitals of power transformer main protection protection, when being short-circuited in the transformer, can produce gas in the transformer, industry is called methane gas, the light gas that slight short circuit produces is floated downward the lubricating cup in the gas relay, connect light gas contact, fault-signal is sent to monitoring equipment by wire circuit; When the transformer internal fault is serious, will produce hydrocarbon flow, the interior baffle plate of relay this moment is got excited by air-flow; relay is thought highly of the gas contacting; send trip signal by circuit to monitoring equipment, switch trip cuts off transformer frequency response automatically, thereby has protected transformer and power system security.Gas relay is malfunctioning will to cause a serious accident, and therefore often will detect gas relay.What adopt at present is that the manual simulation detects, and manually blows to the lubricating cup of relay when detecting light gas, gets in touch the communication testing result by intercom and monitoring equipment supervision personnel; Then need the people to press a probe that links to each other with baffle plate when detecting heavy gas, and get in touch with monitoring equipment.This detection method is unhygienic, blows motionlessly sometimes, causes artificial detection half-hearted easily, and influence detects effect.If transmitting the circuit of signal in addition goes wrong and can't detect.
Summary of the invention
The utility model aims to provide a kind of instrument of the relay of detected gas easily working condition, structure of the present utility model as shown in drawings, the utility model has a housing, at the housing internal fixation air pump, battery, control circuit and ammeter are arranged, two contacts of air pump escape pipe and control circuit extend to outside the housing.Control circuit has two, and one by battery, switch, ammeter and two gas contact testing circuits that the contact is formed; One is a plurality of light gas detection tolerance control circuits that composed in parallel by the resistance of beginning and different resistances between being connected on air pump and battery.Ammeter and each switch are arranged on the surface of housing.For using, easy to carryly on housing, can fixing a belt that has nylon adherent buckle, the utility model can be fixed on testing staff's the wrist.
When the utility model detected light gas, two contacts of ammeter connect the light gas of gas relay contact, to inflation of relay air chamber and venting, observed the duty that the ammeter registration can be judged gas relay.Detect when weighing Buchholz relay, the heavy gas of electrical equipment contact is succeeded in two contacts of ammeter, and the testing staff touches probe, observes the ammeter registration and both can finish detection.The utility model is simple in structure, and is easy to use, can a people finish testing.Whole testing process does not have the oil leakage, does not destroy oil, and the testing process safety and sanitation have improved work quality and work efficiency.
Description of drawings
Accompanying drawing 1 is the utility model outside drawing;
Accompanying drawing 2 is the utility model Buchholz relay contact testing circuit;
Accompanying drawing 3 is the light Device in Gas amount control circuit of the utility model.
Legend: 1, gas relay detector switch; 2, voltage table; 3, light gas detects and adds air cock; 4, air pump tolerance gauge tap; 5, ammeter contact; 6, escape pipe.
Embodiment
Heavy gas testing circuit battery is 12 volts, 250 milliamperes of strength of current, and ammeter adopts voltage table.Light gas detects the tolerance control circuit five shelves is set, and battery is 6 volts of direct currents.Each switch is arranged on surface of shell, and long 90 millimeters of housing is wide 60 millimeters, high 50 millimeters.
Claims (2)
1, the portable gas relay is decided the seizure test device, comprises a housing, it is characterized in that at the housing internal fixation air pump, battery, control circuit and ammeter being arranged, and two contacts of air pump escape pipe and control circuit extend to outside the housing.
2, decide the seizure test device according to the said portable gas relay of claim 1, it is characterized in that on housing, fixing a belt that has nylon adherent buckle.
