Description

Technical Field

[0001] The utility model belongs to the technical field of electrical equipment maintenance, in particular to a transformer oil level gauge float connecting rod detection device platform. Background Art

[0002] The oil conservator is an accessory of the oil-immersed transformer. One of its important functions is to regulate the volume change of the transformer oil: due to temperature changes, the volume of the transformer oil will expand or contract. The oil conservator can compensate for this volume change and ensure that the transformer oil in the tank is always full. The transformer oil level gauge is used to monitor and control the oil level of the power transformer oil conservator. The oil level gauge sensor is installed on the oil conservator, the oil level gauge head is directly installed on the transformer tank wall, and the oil level gauge float connecting rod is installed inside the oil conservator and connected to the oil level gauge head. The indicator instrument and sensor of the oil level gauge are connected with a capillary tube.

[0003] Each time the power transformer is overhauled, the transformer oil in the transformer tank needs to be drained to facilitate the inspection of the internal accessories of the transformer. One of the important links is to check the oil level gauge of the transformer oil storage cabinet to determine whether it meets the conditions for use and whether it can continue to serve. The float of the oil level gauge has been soaked in oil for a long time, and there is a possibility that oil has penetrated into its interior, resulting in inaccurate indication of the oil level gauge. Therefore, an important step in checking the oil level gauge is to separate the oil level gauge float connecting rod from the oil level gauge head, disassemble the float connecting rod, and place it in the oil to observe the buoyancy of the float. Since the float and connecting rod are integrally formed, when testing the buoyancy of the float, it is impossible to simulate the actual environment inside the oil storage cabinet to check the buoyancy of the float. The current practice is that the maintenance personnel put the float at one end of the float connecting rod into the oil and hold the other end with their hands. This practice is affected by the different strength of the maintenance personnel holding the other end with their hands, resulting in changes in the buoyancy of the float, and it is also impossible to compare with multiple float connecting rods. Summary of the invention

[0004] In view of the problems in the above-mentioned prior art that manual detection of float connecting rods is inaccurate and multiple float connecting rods cannot be detected simultaneously, the utility model provides a transformer oil level gauge float connecting rod detection device platform, and its technical solution is: comprising a detection device platform, the detection device platform is composed of side walls and a bottom plate, a plurality of steering plates are arranged on the bottom plate, the steering plate is hinged to one end of the float connecting rod, a float is arranged at the other end of the float connecting rod, the side wall of the detection device platform is connected to the oil filling conduit through a mounting ring, the side wall of the detection device platform is also provided with an oil drain pipe, and a ball valve is arranged on the oil drain pipe.

[0005] As a preferred solution, at least three running wheels are arranged at the bottom of the base plate.

[0006] As a preferred solution, an adjustment frame is arranged outside the side wall of the detection device platform, the adjustment frame is threadedly connected to the support screw, and the bottom end of the support screw is fixedly connected to the support seat.

[0007] As a preferred solution, a handle is provided on the side wall of the detection device platform.

[0008] As a preferred solution, a plurality of level rulers are provided on the top of the side wall of the detection device platform.

[0009] Beneficial effects of the utility model:

[0010] (1) The device can accurately detect the working condition of the float connecting rod and whether it can continue to be used, thereby reducing the error caused by manual detection;

[0011] (2) The device can detect multiple float connecting rods at the same time, compare them with new float connecting rods, and further accurately detect the working conditions of the float connecting rods;

[0012] (3) The device can determine the change in buoyancy of the new and old float connecting rods through two methods: dynamic observation by slow oil injection and static observation after standing for a period of time, and determine whether the operating conditions are met.
