Embodiment

[0033] Such as Figure 1-Figure 4 As shown, the gas relay with independent heavy gas and oil loss functions includes a housing 24, which is equipped with light gas functional components, heavy gas functional components, oil loss functional components and a monitoring system. The following describes each component in detail.

[0034] The heavy gas functional assembly includes a baffle plate 5, a heavy gas magnet seat, and a heavy gas reed switch. There are two heavy gas reed switches, respectively denoted as the first heavy gas reed switch 19 and the second heavy gas reed switch 23. The heavy gas magnet seat is provided with heavy gas magnets, which are respectively recorded as the first heavy gas magnet 20 and the second heavy gas magnet 22, corresponding to the first heavy gas reed switch 19 and the second heavy gas reed switch 23 one by one. The number of groups of heavy gas magnet holder and heavy gas reed switch can also be set to one or three groups, etc., depending on th...

Abstract

The invention relates to a gas relay with independent heavy gas and oil loss functions, wherein the gas relay comprises a shell; a heavy gas function component and an oil loss function component are arranged in the shell, wherein the heavy gas function component comprises a baffle, a heavy gas magnet seat and a heavy gas reed switch, and a heavy gas magnet is arranged on the heavy gas magnet seat;the oil loss function component comprises an oil loss floating ball, an oil loss floating ball bracket, an oil loss magnet and an oil loss reed switch, wherein the oil loss magnet is arranged on an oil loss magnet seat and corresponds to the oil loss reed switch; the lower portion of the baffle is hinged to the first rotating shaft through a connecting piece so that the baffle can rotate by a certain angle under the action of external force, and the connecting piece and the heavy gas magnet base are in linkage assembly. The oil loss floating ball bracket and the oil loss magnet seat are assembled in a linkage manner. When the heavy gas reed switch is triggered, the oil loss reed switch is not triggered, and after the two functions of heavy gas and oil loss are independent, a worker can accurately determine the fault source according to different control circuits.

Description

technical field [0001] The invention relates to the technical field of gas relays, in particular to a gas relay with independent functions of heavy gas and oil loss. Background technique [0002] The device that realizes light gas and heavy gas protection is usually a gas relay (also known as a gas relay). When a fault occurs inside the transformer, such as a discharge fault, the discharge arc decomposes the transformer oil and produces various characteristic gases such as methane, acetylene, hydrogen, carbon monoxide, carbon dioxide, ethylene, and ethane. The more serious the fault, the greater the amount of gas. After the gas is generated, it flows through the gas relay during the process of rising from the inside of the transformer to the upper oil conservator; if the amount of gas is small, the gas accumulates in the gas relay, causing the float to drop, and the light gas reed switch of the relay is triggered to act. The light gas protection sends out a warning signal; ...
