Description

Technical Field

[0001] The utility model relates to the field of electrical measuring equipment, and more specifically, to an insulation resistance tester which is convenient for wire collection. Background Art

[0002] Insulation resistance tester is commonly used to measure the resistance value of various insulating materials, such as measuring the insulation characteristics of motors, cables, transformers and electrical equipment. The insulation resistance tester is a test of the main insulation performance of the transformer. It mainly diagnoses the degree of influence of mechanical, electric field, temperature, chemical and moisture pollution on the transformer. It can sensitively reflect the overall moisture, overall deterioration and insulation penetration defects of the transformer insulation. It is one of the main reference criteria for whether the transformer can be put into operation. During the test, the wire in the tester needs to be electrically connected to the equipment to be tested. When the test is completed, the wire needs to be promptly recovered into the tester.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] See also Figure 1-3 , an insulation resistance tester convenient for winding up, comprising a tester body 1, both sides of the tester body 1 are provided with dustproof mesh holes 2, two support plates 3 are fixedly installed on the inner side of the tester body 1, and a detection board 4 is fixedly installed between the two support plates 3, and the surface of the detection board 4 is provided with evenly distributed heat dissipation holes, which can quickly dissipate heat during the detection process, thereby improving the protection of the detection board, and the top of the detection board 4 is electrically connected with a display panel 5, on which a display screen and a switch button are provided, which are convenient for operation and observation of detection data, and a reduction motor 6 is fixedly installed at the bottom of the detection board 4, and the output end of the reduction motor 6 is provided with fan blades 7 and a push rod 8 from top to bottom in sequence;

[0031] A wire taking-up mechanism 9 is provided inside the tester body 1, and two symmetrical wire holes 10 are provided on the front side of the tester body 1. The inner side of the wire hole 10 is provided with a rubber protective sleeve to protect the wire 11, and the two wire holes 10 are inserted with the wire 11. The other end of the wire 11 is wound around the wire taking-up mechanism 9 and electrically connected to the lower surface of the detection board 4. A clamping mechanism 12 is provided on the front side of the tester body 1.

[0032] When it is necessary to reel in the wire, start the reduction motor 6, and the output end of the reduction motor 6 rotates to drive the fan blades 7 and the push rod 8 to rotate. During the rotation of the push rod 8, it will contact the support rod 94 on the surface of the circular ring 93 in the wire-reeling mechanism 9 and drive the rotation of the support rod 94, so that the circular ring 93 rotates accordingly, and then the wire drum 92 rotates, thereby driving the wire 11 to be continuously wound around the surface of the wire drum 92 to reel in the wire. When the wire reeling is about to be completed, start the clamping mechanism 12 to complete the clamping and fixing of the wire 11 to prevent the wire 11 from falling off from the surface of the wire-reeling mechanism 9 under its own gravity after entering the inside of the tester body 1 from the wire hole 10, which brings inconvenience to the secondary use.

[0033] Embodiment 2:

[0034] See also Figure 4 The difference between the embodiment 1 and the embodiment 1 is that the wire taking-up mechanism 9 includes a round rod 91 rotatably connected to the inside of the tester body 1, a wire drum 92 is fixedly sleeved on the outer surface of the round rod 91, and circular limit baffles are provided on both sides of the surface of the wire drum 92 to prevent the wire 11 from deviating and falling off during winding, a circular ring 93 is fixedly sleeved in the middle of the outer surface of the wire drum 92, and evenly distributed support rods 94 are fixedly connected to the outer surface of the circular ring 93.

[0035] The reduction motor 6 drives the push rod 8 to rotate. The push rod 8 is located between two adjacent support rods 94. As the push rod 8 moves, the support rod 94 is driven to rotate, thereby causing the ring 93 to rotate. The rotation of the ring 93 drives the bobbin 92 to rotate, thereby winding the wire 11 around the surface of the bobbin 92. In addition, the operation of the reduction motor 6 drives the fan blades 7 to rotate, thereby blowing air inside the tester body and accelerating the dissipation of heat.

[0036] Embodiment 3:

[0037] See also Figure 5, which is different from Example 1 in that the clamping mechanism 12 includes a lower clamping plate 121 fixedly connected to the lower front side of the tester body, and two symmetrical electric push rods 1228 are fixedly installed on the top of the lower clamping plate 121, and the output ends of the two electric push rods 1228 are fixedly connected to an upper clamping plate 123, and the sides of the upper clamping plate 123 and the lower clamping plate 121 close to each other are provided with arc-shaped grooves adapted to the wire hole 10. The design of the arc-shaped groove matches the circular cross-section of the wire 11, so that the clamping is more stable and firm.

[0038] When the wire collection is almost completed, the two electric push rods 1228 are started for recovery, which drives the upper clamping plate 123 to move downward, so that the distance between the upper clamping plate 123 and the lower clamping plate 121 is continuously reduced until the surface of the wire 11 is clamped and fixed, preventing the wire 11 from being scattered due to its own gravity after completely entering the main body of the tester.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
