Description

TECHNICAL FIELD

[0001] The utility model relates to an environmental protection cabinet, especially a cable test for the environmental protection cabinet. BACKGROUND

[0002] The whole cabinet structure of the traditional environmental protection cabinet is fully closed, the cable is generally arranged at the lower part of the cabinet, and the grounding point is also arranged in the cabinet, when the functions such as pressure resistance, resistance characteristic and insulation characteristic are tested, the wiring point cannot be found for testing, and it is also impossible to take the point from the equipment or lead the point out for testing, even if the point is led out for testing, it is unsafe and unreliable for the person and the equipment, therefore, it is impossible to test the pressure resistance, resistance and insulation of the whole main circuit from the cable end to the cabinet, which leaves hidden dangers for the quality of the product, and the uncertain factors such as insulation damage, internal short circuit and insufficient safety distance may cause accidents, unnecessary property loss and time waste. SUMMARY

[0003] The utility model discloses a kind of environmental protection cabinet cable test structures, wherein, three-phase test bushing is horizontally arranged at cabinet top, plug is arranged at the front end of test bushing, the rear end of test bushing is connected to the grounding position of three-position disconnecting circuit breaker of cabinet through connecting copper bar, test door is opened in the panel of cabinet opposite three-phase test plug, the test door is connected to the grounding of three-position disconnecting circuit breaker, short-circuit copper bar is arranged in the test door, test plug can be inserted into short-circuit copper bar, short-circuit copper bar is connected to cabinet main grounding through main grounding copper bar.

[0004] After using the above scheme, the cabinet type of the environmental protection cabinet cable test function is simple and convenient to operate, safe and reliable, reduces manpower investment, and improves work efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0011] In order to make the technical contents, construction features, purposes and effects of the utility model clear, the following will be described in detail in combination with the embodiments and the drawings.

[0012] Please refer to Figure 1 and Figure 2 The utility model discloses an environmental protection cabinet cable test structure, three -phase test bushings 1 are arranged on the upper part of the cabinet, and the test bushings 1 are connected to the grounding position of the three-position disconnecting switch of the cabinet through the connecting copper bar 8, the front end of the test bushings 1 is equipped with the plug (copper column) 3, and the test door 2 is set up on the cabinet panel corresponding to the test bushings 1, in order to guarantee the test safety, the test door 2 is connected to the grounding of the three-position disconnecting switch (that is, the test door 2 can be opened only when the three-position disconnecting switch is grounded, and this part is the conventional means in the field, and the application will not be described), the short-circuit copper bar 4 is arranged in the test door, the short-circuit copper bar 4 can be provided with three plug-in holes and is inserted into the plug 3 of the test bushings 1, or the short-circuit copper bar 4 is provided with a groove, and the plug 3 is inserted into the groove, one end of the short-circuit copper bar 4 is rotatably hinged to the side wall of the cabinet, and the short-circuit copper bar 4 is connected to the main grounding copper bar 6 and then connected to the main grounding of the cabinet.

[0013] When working, as shown in Figure 3 , the three-position disconnecting switch is in the grounding work, and the test door handle 6 is pulled out, the test door 2 is opened, the short-circuit copper bar 4 is withdrawn from the plug 1 of the test bushings 1, and the test instrument is directly clamped to the copper column of the plug of the test bushings and tested.

[0014] The above-mentioned is only the embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent shape or structural transformation using the contents of the utility model specification and drawings or directly or indirectly applied in other related technical fields is also included in the patent protection range of the utility model.
