Abstract
Description
Technical Field
[0001] The utility model belongs to the technical direction of electrical equipment detection, and specifically relates to a time identification auxiliary device. Background Art
[0002] During the testing process, electrical equipment will test the power on and off time, but this test is not very accurate, the error is relatively large, and it can only be measured to seconds. Utility Model Content
[0003] The purpose of the utility model is to assemble the existing equipment to solve the problems raised in the above background technology.
[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a time identification auxiliary device, including a ground resistance tester, a current relay, and a digital electric stopwatch, characterized in that: a current relay is arranged on the upper part of the ground resistance tester, a digital electric stopwatch is arranged on the upper part of the current relay, the ground resistance tester and the current relay are connected by a wire, and an air-touch switch is arranged between the current relay and the digital electric stopwatch.
[0005] Beneficial effects of the utility model:
[0006] Compared with the prior art, the utility model utilizes the ground resistance tester, current relay and digital electric stopwatch on the existing market, and utilizes the accuracy of the digital electric stopwatch to measure the tested equipment. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:
[0008] Figure 1 It is the overall structure diagram of the utility model. DETAILED DESCRIPTION
[0009] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.
[0010] A time identification auxiliary device comprises a ground resistance tester 1, a current relay 2, and a digital electric stopwatch 3, wherein the characteristics are as follows: the current relay 2 is arranged on the upper part of the ground resistance tester 1, the digital electric stopwatch 3 is arranged on the upper part of the current relay 2, the ground resistance tester 1 is connected to the current relay 2 through a wire, and an air-contact switch is arranged between the current relay 2 and the digital electric stopwatch 3. When the digital electric stopwatch 3 is turned on, the digital electric stopwatch 3 starts counting. Since the accuracy of the digital point stopwatch 3 is at the millisecond level, the accuracy of the millisecond level is used to calibrate the second-level electrical equipment, and the accuracy is relatively high.
[0011] When the ground resistance tester 1 is turned on, current output is realized. After receiving the current, the current relay 2 starts working and gives a signal. The digital stopwatch 3 receives the signal and starts timing. The digital stopwatch 3 adopts the 415 type. This model of digital stopwatch 3 has good stability and high precision. There are multiple wiring methods. After the wire clamp is connected to the electrical equipment, the conduction timing is realized, and the timing stops after the power is cut off. This working principle eliminates human interference.
[0012] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0013] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them. Although the utility model is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
