Description

Technical Field

[0001] The utility model relates to the field of electrical equipment, in particular to an insulating shaking test drawer dedicated to an electrical low-voltage cabinet. Background Art

[0002] Insulation testing, a routine task in substation maintenance, is frequent and carries significant risks. Currently, low-voltage cabinet manufacturers have not considered the dangers of insulation testing and implemented appropriate measures. When performing insulation testing behind the cabinet on multiple feeder circuits within a single cabinet, close contact with live parts of the equipment is unavoidable, potentially causing personal injury and equipment short-circuit failures. Using an insulation testing drawer cabinet for this operation can significantly reduce the likelihood of accidents, ensuring both personal and equipment safety. Utility Model Content

[0003] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a drawer device that can simplify the insulation shaking test process, reduce the risk of electric shock for substation operation and maintenance personnel working behind the cabinet, and ensure the safety of people and equipment.

[0004] In order to solve the above problems, the technical solution of the utility model is: an insulation shaking test drawer dedicated to an electrical low-voltage cabinet, comprising a drawer, two contact assemblies and a connecting plug;

[0005] The two contact assemblies are respectively located on one side of the drawer and are provided with three evenly distributed connection plugs. A grounding connection point is provided on the front of the drawer, and a positioner is fixedly connected to the back side of the drawer.

[0006] Furthermore, a phase color mark is provided on the contact assembly located above the connecting plug. The phase color mark is divided into three colors, and the A, B, and C phase sequences correspond to yellow, green, and red.

[0007] Furthermore, handles are fixedly connected to the left and right sides of the front of the drawer.

[0008] Furthermore, the positioner is composed of two positioning pins.

[0009] The advantages of this utility model compared with the existing technology are:

[0010] The utility model is provided with a drawer. By utilizing the contact assemblies on the front and rear sides of the drawer and the three connecting plugs thereon, the industry habit of testing the insulation of cables and equipment from the back of the low-voltage cabinet can be changed to operating from the front of the cabinet, thereby simplifying the insulation testing process, reducing the risk of electric shock for substation operation and maintenance personnel working behind the cabinet, and ensuring personal and equipment safety.

[0014] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0015] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0016] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0017] like Figures 1 to 2 As shown, an insulation shaking test drawer specially used for an electrical low-voltage cabinet comprises a drawer 1, two contact assemblies 2 and a connecting plug 3; the two contact assemblies 2 are respectively located on one side of the drawer 1, and are provided with three evenly distributed connecting plugs 3 thereon, the six connecting plugs (3) at the front and rear are grouped in two and connected using a connecting wire (4), a grounding connection point 7 is provided on the front of the drawer 1, a positioner 8 is fixedly connected to the rear side of the drawer 1, the positioner 8 is composed of two positioning pins, a phase color mark 5 is provided on the contact assembly 2 above the connecting plug 3, the phase color mark 5 is divided into three colors, and the phase sequence A, B, and C correspond to yellow, green, and red, and a handle 6 is fixedly connected to the left and right sides of the front of the drawer 1.

[0018] In actual use, a drawer cabinet for insulation testing of low-voltage equipment in substations is made to carry out insulation testing of cables and equipment to be tested without opening the back door of the cabinet, thereby avoiding safety accidents caused by accidentally entering live intervals or accidentally touching live parts.

[0019] The commissioning of the insulation test drawer cabinet for low-voltage equipment in substations has reduced the risk of substation operation and maintenance, reducing the occurrence of electric shock accidents and ensuring the safety of personnel during daily equipment maintenance and fault detection.

[0020] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
