Description

Technical Field

[0001] The utility model relates to the field of distribution boxes, in particular to a distribution box with a withdrawable unit detection device. Background Art

[0002] In the past, power-on inspection processes typically involved inspecting the entire cabinet. The drawout units were then fabricated separately after the cabinet body was completed. Often, the cabinet body had to wait until the drawout units were finished before the full cabinet inspection could begin. This involved multiple steps in the full cabinet inspection, resulting in a high error rate and lengthy inspection times, impacting project delivery. Utility Model Content

[0003] In order to solve the above problems, the present technical solution provides a distribution box with a withdrawable unit detection device.

[0004] To achieve the above purpose, the technical solution is as follows:

The wiring room has a wiring system to connect the various units. The leakage protection switch room receives external electrical energy and outputs it to the power supply test room, which supplies energy to the two withdrawable unit modules.

[0006] In some embodiments, a partition for supporting the pull-out unit module is provided inside the box body, guide rails are provided on both sides of the partition, and sliding parts movable on the guide rails are provided on both sides of the pull-out unit module.

[0007] In some embodiments, the guide rail is provided with a positioning portion at the front end, the outer side of the positioning portion is a guiding design, and the inner side is an abutment surface;

[0008] The sliding portion is provided with a stopper matched with the abutting surface.

[0009] In some embodiments, the pull-out unit module includes a bottom plate and a rear plate, and the rear plate is provided with two rows of terminal blocks for electrical connection.

[0010] In some embodiments, a wiring system for electrically connecting to the terminal block is provided on the rear side of the box body.

[0011] The beneficial effects of this application are:

[0012] To improve inspection efficiency and error rates, this application separately inspects the withdrawable unit and develops a power-on detection device for the withdrawable unit. This application offers advantages such as simple structure, modularity, easy maintenance, and economical reliability. This modularity allows for the same accessories to be configured for withdrawable unit inspections based on the current configuration, making module replacement quick and easy.

[0015] Figure 2 This is a schematic diagram of the structure of the embodiment of the utility model Figure 2 ;

[0016] Figure 3 This is a schematic diagram of the structure of the embodiment of the utility model Figure 3 . DETAILED DESCRIPTION

[0017] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] Please refer to Figure 1-3 As shown, a distribution box with a withdrawable unit detection device includes a box body, and the box body is provided with a wiring room 1, a leakage protection switch room 2, a power supply test room 3 and two withdrawable unit modules 4 from the upper end to the lower end. The wiring room 1 has a wiring system to connect each unit. The leakage protection switch room 2 receives external electric energy and outputs it to the power supply test room 3. The power supply test room 3 and the two withdrawable unit modules 4 supply energy.

[0019] The upper part of the box body is the control and protection system for the test power supply. The leakage protection switch room has a leakage protection type main switch, which is responsible for controlling the access of the external power supply. The power supply test room is an external button that controls the internal contactor to allow power to be passed to the product under test for power-on debugging, which improves the safety of the device. The tester controls the power through two switches to power the load in the withdrawal unit module, thereby completing the test process.

[0020] The main frame of the box body is made of 2.0 thick C profile, and is covered with magic holes at 25MM intervals.

[0021] In this embodiment, a partition 5 for supporting the pull-out unit module 4 is provided inside the box body, guide rails 6 are provided on both sides of the partition 5, and sliding parts 7 movable on the guide rails 6 are provided on both sides of the pull-out unit module 4.

[0022] When the module is pulled out, the sliding part slides on the guide rail to facilitate the staff to pull it out or push it in, and the operation is convenient.

[0023] In this embodiment, the guide rail 6 is provided with a positioning portion 8 at the front end. The outer side of the positioning portion 8 is a guiding design, and the inner side is an abutting surface.

[0024] The sliding portion 7 is provided with a stopper 9 that cooperates with the abutting surface.

[0025] When the module is pushed in, the guide shape makes it easier to push the module into the interior. In addition, when it is pulled out, the cooperation between the abutment surface and the stop portion controls the withdrawal stroke to prevent it from falling off.

[0026] In this embodiment, the drawer unit module 4 includes a bottom plate and a rear plate 11 . The rear plate 11 is provided with two rows of terminal blocks 12 for electrical connection to facilitate wiring.

[0027] In this embodiment, a wiring system 13 for electrically connecting to the terminal block 12 is provided on the rear side of the box body.

[0028] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other embodiments whose principles and basic structures are the same or similar to those of the present application are within the scope of protection of the present application.
