Description

Technical Field

[0001] This utility model relates to the technical field of dielectric strength testers, and specifically to a dielectric strength tester. Background Technology

[0002] To ensure the quality and safe use of hydraulic oil, lubricating oil, transformer oil, and other fluids, it is often necessary to perform dielectric strength testing, which requires the use of dielectric strength testing equipment.

[0003] For example, the dielectric strength tester disclosed in Chinese Patent Publication No. CN220820157U describes a method for stirring oil poured into an insulating sleeve. The method involves a motor driving a magnetic ring to rotate via gear meshing. The magnetic field of the magnetic ring passes through the bottom of the insulating sleeve and is conducted to the magnetic rod inside the rotating rod. This causes the rotating rod to rotate inside the insulating sleeve via a shaft, thus stirring the oil. This effectively prevents oil leakage through gaps caused by wear between the drive shaft and the insulating sleeve. However, this method has the following technical problems:

[0004] The motor rotates at a high speed. When the gears and teeth drive the magnetic ring to rotate, the magnetic ring has a ring structure, which makes it difficult for the magnetic ring to work with the magnetic rod to drive the rotating rod to rotate when it rotates at high speed. This makes it impossible for the rotating rod to stir the oil. Utility Model Content

[0005] Therefore, this utility model provides a dielectric strength tester to solve the problem in the prior art that the magnetic ring is difficult to cooperate with the magnetic rod to drive the rotating rod to rotate when it rotates rapidly.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dielectric strength tester includes a tester body for testing oil.

[0008] The detector body includes a detection box, inside which are installed multiple detection cylinders for holding oil, and electrodes are installed inside the detection cylinders.

[0009] The upper end of the testing box is equipped with a stirring device, which includes a power box. The power box includes a stirring rod for stirring the oil inside the testing cylinder. Multiple positioning blocks are installed on the outer wall of the power box, and a positioning groove is provided at the lower end of each positioning block.

[0010] The detection box includes a locking ring, and the upper end of the locking ring is equipped with multiple limiting rods for stabilizing the power box.

[0011] Furthermore, an air inlet pipe is installed at the right end of the testing box, and a filter screen is installed inside the air inlet pipe. An air outlet pipe is installed at the right end of the testing box, and a fan is installed inside the air outlet pipe.

[0012] Furthermore, a display screen is installed at the front end of the detection box, and a first limiting ring and a second limiting ring are installed on the upper inner wall of the detection box for limiting the locking ring. The middle part of the first limiting ring is provided with multiple sliding grooves to facilitate the sliding of the limiting rod.

[0013] Furthermore, the upper end of the detection box is equipped with multiple positioning vertical rods for positioning the power box. The lower end of the positioning vertical rod is provided with a positioning groove, and one end of the limiting rod is inserted into the positioning groove. The upper end of the first limiting ring is equipped with a stop block, and a magnetic block is installed inside the stop block.

[0014] Furthermore, a handle is installed on the outer wall of the locking ring, and a second magnetic block is installed inside the limiting rod, which is magnetically attracted to the first magnetic block.

[0015] Furthermore, an arc-shaped frame is installed at the upper end of the power box, a slot for engaging with the positioning vertical rod is opened in the middle of the positioning block, a plug for sealing the detection cylinder is installed at the lower end of the power box, a gear one is installed at the upper end of the stirring rod, a gear two is meshed at one end of the gear one, and the gear two controls the rotation of multiple stirring rods, and a motor is installed at the upper end of the gear two.

[0016] This utility model has the following advantages:

[0017] When the power box is installed on the top of the test box, the stirring rod is inserted into the inside of the test cylinder, and the stopper seals the top of the test cylinder. The positioning rod is inserted into the slot of the slot to limit the power box. When the arc frame and the top of the test box abut, the second positioning slot and the first positioning slot are aligned. By holding the handle, the locking ring is rotated, and the arc plate of the limiting rod is inserted into the slot of the first positioning slot through the second positioning slot. At this time, the second magnetic block and the first magnetic block are magnetically attracted to each other, thereby locking the power box.
