Description

Technical Field

[0001] The utility model relates to the technical field of transformer oil chromatography equipment, in particular to a transformer oil chromatography equipment base. Background Art

[0002] Transformer oil chromatography equipment is an instrument used to determine the component content of dissolved gases in transformer oil. It is mainly used in power systems to ensure the safety and efficient operation of the power grid. By performing quantitative and qualitative analysis on the mixture, it can also determine the sample's physical and chemical constants such as the distribution coefficient, activity coefficient, molecular weight and specific surface area on the stationary phase.

[0003] For example, Chinese patent publication number CN217007151U discloses a transformer oil chromatograph, the technical solution of which comprises a housing having a detection slot formed on one side of the housing, an air extraction hole formed on the top surface of the housing, and a PLC panel connected to one side of the housing; a door disposed within the detection slot; a purification box connected to the right side of the housing, a fixing slot formed on the top surface of the purification box; and a purification assembly disposed within the purification box for purifying residual gas within the housing.

[0004] In the aforementioned reference document, a purification column is provided. The staff rotates the sealing cover to remove it from the interior of the installation slot. At this time, the staff inserts the purification column into the installation slot. The adsorption column installed in the instrument slot opened on the outer wall of the purification column adsorbs the residual gas. The interior of the adsorption column is filled with activated carbon. The strong adsorption force of the activated carbon prevents the accuracy of the next test from being affected.

[0005] However, when the base of the transformer chromatography equipment is actually used, the insulating oil tank is placed on the base inside the shell for detection. The insulating oil tank is taken out from the narrow space inside the shell, which is very inconvenient to operate. In addition, there is no fixing mechanism for the insulating oil tank on the base of the equipment inside the shell, resulting in insufficient stability of the insulating oil tank and easy spillage of the internal transformer insulating oil. Utility Model Content

[0006] The purpose of the utility model is to provide a transformer oil chromatography equipment base, which can be conveniently slid out of the shell, so that the insulating oil tank is more convenient to take and put. At the same time, the equipment base can conveniently position the insulating oil tank, so that the insulating oil in the insulating oil tank is better placed during testing.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a transformer oil chromatography equipment base, comprising a shell and an equipment base, the equipment base being movably installed in the inner wall of the shell, a rotating block being rotatably installed on the top of the equipment base through a rotating shaft, a positioning seat being detachably installed on the top of the rotating block, a ball screw slide being provided between the inner wall of the shell and the equipment base, a servo motor being fixedly installed on the bottom of the equipment base, an output end of the servo motor being fixedly connected to the rotating shaft at the bottom of the rotating block, positioning rods being connected through the top circumference of the rotating block at equal intervals, and a positioning plate being fixedly connected to the top of the positioning rods.

[0008] Preferably, a sealing door is movably installed at the front opening of the shell, and a control panel is fixedly installed on the front of the sealing door.

[0009] Preferably, a mounting groove is provided at the bottom of the inner wall of the shell, and the ball screw slide is fixedly installed in the inner wall of the mounting groove.

[0010] Preferably, the equipment base is fixedly mounted on a matching slider on the top of the ball screw slide.

[0011] Preferably, a clearance groove is provided at the bottom of the equipment base, and the servo motor is fixedly installed in the inner wall of the clearance groove.

[0012] Preferably, a guide groove is provided on the top of the equipment base, and positioning grooves are provided at equal intervals on the circumference of the top of the rotating block, and the guide grooves correspond to the positioning grooves one by one.

[0013] Preferably, both ends of the positioning rod slide in the guide groove and the inner wall of the positioning groove respectively.

[0014] Preferably, a fixing groove is provided on the top of the rotating block, and the threaded block at the bottom of the positioning seat is installed in the mounting hole on the inner wall of the fixing groove through threads.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model discloses that the transformer insulating oil tank can be placed on the positioning seat, and the rotating block is driven to rotate by the output end of the servo motor. The positioning rod on the top of the rotating block can converge and expand along the guide groove under the cooperation of the guide groove and the positioning groove. In this way, the positioning plate on the top of the positioning rod can clamp and fix the transformer insulating oil tank, so that the insulating oil in the insulating oil tank is placed more stably during detection, and the insulating oil in the insulating oil tank is prevented from shifting and spilling. This solves the problem that the insulating oil tank is not stable enough and the insulating oil of the transformer inside is easily spilled due to the lack of a fixing mechanism for the insulating oil tank on the base of the equipment inside the shell.

[0017] When the insulating oil tank is placed on the positioning seat, the matching slider in the ball screw slide can drive the positioning seat to slide from the shell to the outside along the ball screw slide. In this way, when the transformer insulating oil to be tested is placed on the positioning seat, there is no need to put hands into the shell to take and place the insulating oil tank. The insulating oil tank can be taken and placed from the outside of the shell, which makes it more convenient to take and place the insulating oil tank. This solves the problem of inconvenience in taking and placing the insulating oil tank from the narrow space inside the shell when the insulating oil tank is placed on the base inside the shell for testing.

Positioning rods 32 are connected through the top circumference of the rotating block 3 at equal intervals. A positioning plate 33 is fixedly connected to the top of the positioning rods 32.

[0026] The transformer insulating oil tank can be placed in the positioning seat 4, and the rotating block 3 is driven to rotate by the output end of the servo motor 6. The positioning rod 32 on the top of the rotating block 3 can converge and expand along the guide groove 21 under the cooperation of the guide groove 21 and the positioning groove 31. In this way, the positioning plate 33 on the top of the positioning rod 32 can clamp and fix the transformer insulating oil tank, so that the insulating oil in the insulating oil tank is placed more stably during testing, and the insulating oil in the insulating oil tank is prevented from shifting and spilling.

[0027] When the insulating oil tank is placed on the positioning seat 4, the matching slider in the ball screw slide 5 can drive the positioning seat 4 to slide along the ball screw slide 5 from the shell 1 to the outside. In this way, when the transformer insulating oil to be tested is placed on the positioning seat 4, there is no need to reach into the shell 1 to take and place the insulating oil tank. It can be taken and placed from the outside of the shell 1, which makes it more convenient to take and place the insulating oil tank.

[0028] Among them, a sealed door 11 is movably installed at the front opening of the shell 1, and a control panel 12 is fixedly installed on the front of the sealed door 11. A transformer oil chromatograph is installed above the equipment base 2 in the inner cavity of the shell 1. By placing the transformer insulating oil tank on the equipment base 2, the upper transformer oil chromatograph can be controlled by the control panel 12 to detect the insulating oil in the transformer oil tank.

[0033] Then, the transformer insulating oil tank can be placed in the positioning seat 4, and the rotating block 3 is driven to rotate by the output end of the servo motor 6. The positioning rod 32 on the top of the rotating block 3 can be aggregated along the guide groove 21 under the cooperation of the guide groove 21 and the positioning groove 31, so that the positioning plate 33 on the top of the positioning rod 32 can clamp and fix the transformer insulating oil tank, and through the cooperation of the ball screw slide 5, the positioned transformer insulating oil tank can be moved to the lower part of the chromatographic instrument in the inner cavity of the shell 1 for detection, so that the insulating oil in the insulating oil tank is placed more stably during detection, and the insulating oil in the insulating oil tank is prevented from shifting and spilling;

[0034] After the transformer insulating oil tank is placed on the equipment base 2, the transformer oil chromatograph above can be controlled by the control panel 12 to detect the insulating oil in the transformer oil tank;

[0035] Finally, after the chromatographic instrument detects the transformer oil in the insulating oil tank on the equipment base 2, the sealed door 11 can be opened, and the insulating oil tank can be slid out of the housing 1 by cooperating with the slider in the ball screw slide 5, and the insulating oil tank positioned on the positioning seat 4 can be removed.
