Description

Technical Field

[0001] The utility model relates to the field of detection devices, in particular to an adjustable test device for a switch cabinet. Background Art

[0002] In order to ensure that the switch cabinet can operate normally in subsequent use, it is necessary to first conduct effective testing on the switch cabinet. Among them, the power frequency withstand voltage test is the key test to evaluate the insulation performance of the switch cabinet.

[0003] The equipment for power frequency withstand voltage test generally includes transformer, coupling capacitor, resistor and control console, etc. In order to enable the staff to better conduct the power frequency withstand voltage test, each part will be installed on the upper end of the mounting plate, and moved by the roller at the lower end of the mounting plate, so that the staff can more conveniently move the device and adjust the position. In the process of the test, the corresponding parts will be connected with lines to enable the device to operate normally;

[0004] However, the existing mounting plate can only install components and has a single function. When the corresponding components are connected to the lines, the lines will cross and overlap, which not only affects the installation and connection of the lines by the workers, but also affects the workers' movement back and forth, causing danger. For this reason, we proposed an adjustable test device for switch cabinets to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. 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 those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 3 The utility model provides a technical solution: an adjustable test device for a switch cabinet, including a mounting plate 100, a transformer 101, a capacitor 102 and a resistor 103. The mounting plate 100 is set to be U-shaped, and the U-shaped inner wall of the mounting plate 100 is symmetrically provided with slide grooves 104, and sliders 105 are slidably provided inside the two slide grooves 104. An extension plate 106 is fixed between the two sliders 105. The transformer 101 is installed on the upper end of the mounting plate 100, and the capacitor 102 is installed on the rear side of the upper end of the extension plate 106. The two ends of the resistor 103 are respectively connected to the transformer 101 and the capacitor 102. The transformer 101 and the capacitor 102 are both provided with connectors 107 at the lower ends of the outer sides. A wire management component is provided on the front side of the upper end of the mounting plate 100, and a locking component is provided between the extension plate 106 and the mounting plate 100.

[0027] The cable management assembly includes a vertical plate 108, which is fixedly connected to the upper end of the mounting plate 100 and is located in front of the transformer 101. A plurality of evenly distributed grooves 109 are symmetrically opened at the left and right ends of the vertical plate 108, and a plurality of cable clamping grooves 110 are opened on the lower wall of each groove 109 and the upper end of the vertical plate 108.

[0028] The transformer 101, capacitor 102, resistor 103 and external controller are all common equipment in the power frequency withstand voltage test. Their specific functions are not described in detail here. The connector 107 of the transformer 101 and capacitor 102 is connected to the controller through lines. During the connection process, the staff can directly clip the line into the wire slot 110 at the upper end of the vertical plate 108, or clip the line into the corresponding wire slot 110 on the lower side through the groove 109. In this way, the line arrangement can be more neat and orderly, which is convenient for the staff to find and connect later.

[0029] See also Figure 4-Figure 5 The locking assembly includes a latch 200, a movable cavity 201 is opened on one side of the U-shaped inner wall of the mounting plate 100, and the movable cavity 201 is connected to the rear end of the mounting plate 100, the latch 200 is slidably arranged inside the movable cavity 201, and a slot 202 corresponding to the movable cavity 201 is opened on one side of the extension plate 106.

[0030] Two card slots 203 communicating with the moving cavity 201 are formed at the rear end of the mounting plate 100 , and a card block 204 matching the two card slots 203 is formed on the outer side of the latch 200 .

[0031] A groove 205 is formed at the rear side of the lower end of the extension plate 106 .

[0032] A support column 206 is provided in the middle of the rear side of the lower end of the extension plate 106 , and a ball bearing 207 is embedded and rotatably disposed at the lower end of the support column 206 .

[0033] The card block 204 can be inserted into the card slot 203, so that the pin 200 is restricted in the movable cavity 201. When the staff flips the card block 204 upward, the staff can move the pin 200 in the movable cavity 201, and then disengage the pin 200 from or insert it into the slot 202, thereby completing the control of the state of the extension plate 106. When the extension plate 106 is unlocked, the staff can pull the pull slot 205 to move the extension plate 106, thereby adjusting the distance between the capacitor 102 and the transformer 101, which is suitable for testing different types of switch cabinets. During the movement of the extension plate 106, the ball 207 contacts the ground, which can not only support the part of the plate surface extending out of the extension plate 106, but also reduce the friction between the ground, so that the extension plate 106 moves more smoothly.

[0034] See also Figure 3 Support rods 208 are provided at the four corners of the lower end of the mounting plate 100, and a connecting block 209 is rotatably provided at the lower end of each support rod 208. A protective cover 210 is fixed at the lower end of each connecting block 209, and a roller 211 is rotatably provided inside the lower end of each protective cover 210.

[0035] An L-shaped locking block 212 is rotatably provided on the outer side of each protective cover 210 , and a stepping block 213 is fixed to both left and right ends of each L-shaped locking block 212 .

[0036] The protective cover 210 can protect the roller 211 and prevent the impurities on the road from damaging the roller 211 during the movement of the device. Since the support rod 208 is rotatably connected to the connecting block 209, the connecting block 209 can make the roller 211 rotate 360 ​​degrees horizontally during the movement of the entire device, so as to prevent the roller 211 from getting stuck and affecting the movement of the device.

[0037] When the device moves to a suitable position, the staff can step on any pedal block 213 to drive the L-shaped locking block 212 to rotate and make the L-shaped locking block 212 stuck between the roller 211 and the ground, thereby completing the locking of the roller 211. After lifting the pedal block 213, the restriction of the L-shaped locking block 212 on the roller 211 can be released, so that the device can move.
