Description
Technical Field
The utility model relates to a pressure release valve technical field specifically is a clamp plate is used in calibration of transformer pressure release valve.
Background
The operational reliability of the pressure relief valve, one of the most important non-electrical protection devices for the transformer, is directly related to the safety of the transformer. When a fault occurs in the transformer, a large amount of gas generated by the fault can cause the internal pressure of the transformer to increase, the pressure needs to be released through the pressure release valve, and if the pressure release valve cannot correctly act to release the pressure, the transformer is likely to be disassembled due to the overlarge internal pressure. In order to ensure the safe and stable operation of the pressure relief valve, the southern power grid overhaul test regulations stipulate that the action value of the pressure relief valve of the transformer needs to be checked regularly.
In current practice, when calibrating a pressure relief valve, there are generally two methods: firstly, a special inflating instrument is used, and the action pressure of a pressure release valve is recorded by accurately inflating gas with specific pressure; and secondly, a pressure plate with certain weight is applied to the top of the pressure release valve, and the pressure applied to the pressure release valve is calculated by changing the weight of the pressure plate. Among them, the former method requires a special instrument, is expensive, and is complicated in operation and inconvenient for field development. The latter requires a constant change in the weight of the pressure plate during the calibration to change the pressure applied to the pressure relief valve, which is time consuming and results in insufficient accuracy due to the inability to continuously adjust the weight of the pressure plate.
Therefore, a novel pressure plate for checking the pressure relief valve of the transformer is provided to solve the problems.
