Description

Technical Field

[0001] The utility model belongs to the technical field of switch cabinet insulation detection, and specifically relates to a simple insulation measurement device for a 400V switch cabinet. Background Art

[0002] In the 400V switch cabinet at each production site, there are multiple 400V switches, and the three-phase outgoing line distance of each switch is very small.

[0003] For the insulation measurement of the switch in the 400V switch cabinet, the current conventional practice is to have two staff members, one as a supervisor to execute the operation ticket and measure the insulation value of the electrical equipment, and the other as an operator, wearing insulating gloves and using the positive and negative poles of the multimeter to connect the three-phase output lines of the 400V switch respectively.

[0004] The current problem with this method is that since the distance between the three-phase outgoing lines in the 400V switch cabinet is very small, the operating space for two workers when performing insulation measurement is very narrow, and the operation is cumbersome and difficult. In addition, when performing insulation measurement on the standby power, if the switches of the upper and lower equipment are in operation, there is a risk of electric shock, and the safety is low. Utility Model Content

[0005] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a simple insulation measurement device for a 400V switch cabinet which can be completed by one person and greatly reduces the risk of electric shock for operators.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0007] A simple insulation measuring device for a 400V switch cabinet comprises a first insulating handle, wherein two ends of the first insulating handle are a gripping end and a connecting end, respectively, and the connecting ends are respectively connected to a second insulating handle and a third insulating handle through a first coupling;

[0008] One end of the second insulating handle is connected to the first insulating handle, and the other end is connected to a fourth insulating handle via a second coupling;

[0009] One end of the third insulating handle is connected to the first insulating handle, and the other end is connected to the fifth insulating handle via a third coupling;

[0010] One end of the fourth insulating handle and the fifth insulating handle are connected to the second insulating handle and the third insulating handle respectively, and the other end is provided with a fixing nut capable of connecting the positive and negative poles of a multimeter respectively;

[0011] Circlips are provided on the first coupling, the second coupling, and the third coupling, enabling the first insulating handle to perform circular motion centered on the axis with the second insulating handle, the first insulating handle and the third insulating handle, the second insulating handle and the fourth insulating handle, and the third insulating handle and the fifth insulating handle.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] When using the simple insulation measuring device designed with this solution for insulation detection, the operator only needs to fix the positive and negative test leads of the multimeter through the fixing nut, and then hold the first insulating handle with one hand, and adjust the rotation angles of the fourth insulating handle and the fifth insulating handle through the other hand and the design of the coupling, so as to realize the insulation detection of the switch in the 400V switch cabinet by a single person. In addition, the structure designed in this solution also has the advantages of simple operation and convenient use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present utility model will be further described below in conjunction with specific embodiments.

[0018] As Figure 1 and 2 shown, the simple insulation measuring device for a 400V switch cabinet described in the present utility model includes a first insulating handle 11. The two ends of the first insulating handle 11 are respectively a holding end and a connection end 1, and the connection end 11 is respectively connected to a second insulating handle 12 and a third insulating handle 13 through a first coupling 21.

[0019] Subsequently, one end of the second insulating handle 12 is connected to the first insulating handle 11, and the other end is connected to the fourth insulating handle 14 through the second coupling 22. Correspondingly, one end of the third insulating handle 13 is connected to the first insulating handle 11, and the other end is connected to the fifth insulating handle 15 through the third coupling 23. One ends of the fourth insulating handle 14 and the fifth insulating handle 15 are respectively connected to the second insulating handle 12 and the third insulating handle 13, and the other ends are respectively provided with fixing nuts 3 capable of connecting the positive and negative poles of a multimeter.

[0020] Circlips are provided on the first coupling 21, the second coupling 22 and the third coupling 23, so that the first insulating handle 11 and the second insulating handle 12, the first insulating handle 11 and the third insulating handle 13, the second insulating handle 12 and the fourth insulating handle 14, and the third insulating handle 13 and the fifth insulating handle 15 can all perform circular motion centered on the axis.
