Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] It is worth noting that the orientation words such as "up" and "down" involved in this article are all determined relative to the perspective of the drawings, and are only for the convenience of description, and cannot be understood as limitations on the technical solution.
[0030] Such as figure 1 As shown, in the conventional transformer electrical performance test, the test clamp 2 is generally clamped on the high voltage side bushing 1 of the transformer, and the test voltage line 21 and the test current line 22 are respectively electrically connected to the corresponding test instruments, but this There are many defects in the connection method. It is necessary for the test personnel to take a bucket arm truck or use a ladder to climb to the corresponding position on the high voltage side of the transformer for wiring. Climbing the bushin...

The invention relates to a suspension type multifunctional transformer test wiring device for 110kV and above transformers, the device comprises a test part connected with a high-voltage side sleeve of a transformer and a height-adjustable insulating rod connected with the test part, wherein the test part comprises a right-opened C-shaped current conducting plate and a left-opened voltage conducting plate, the upper end of the voltage conducting plate is embedded into the current conducting plate, the upper end of the voltage conducting plate embedded into the current conducting plate is wrapped by an insulating layer, and the upper end of the current conducting plate is provided with an insulating fixed end fixedly connected with the voltage conducting plate and a current wiring end capable of being connected with a circuit; the side surface of the voltage conductive plate is provided with a voltage wiring end which can be connected with a circuit, and the top end of the insulating rod is provided with a conductive pressing part which is screwed into the voltage conductive plate and clamps a high-voltage side sleeve of the transformer with the current conductive plate. According to the invention, the problem that a tester needs to climb back and forth during the electrical performance test of the transformer is solved, and the accident potential of high-altitude falling is avoided.
Description
technical field [0001] The invention relates to the field of electrical preventive tests for transformers, more specifically, it relates to a suspended multifunctional transformer test wiring device for 110kV and above transformers. Background technique [0002] At this stage, the electrical performance test items of transformers with voltage levels of 110kV and above include DC resistance, insulation resistance and dielectric loss tests. Usually, the lead clamp of the test instrument is clamped on the high-voltage side bushing of the transformer for testing, such as figure 1 As shown, but this clamping method has the following problems: 1. The contact area between the test clamp and the bushing on the high voltage side of the transformer is small, and there will be problems such as large test current and easy heating of the test clamp, resulting in inaccurate test data; 2. Improper force of the manual operation test clip will make the test clip easy to fall off, requiring t...
