[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 2 and Figure 4 As shown, in this embodiment, an insulating switch cabinet with a leakage alarm function includes a cabinet 1, which is characterized in that: a moving component 9 is installed inside the cabinet 1, and the moving component 9 includes a screw rod 901 rotatably connected to one side of the inner wall at one end of the cabinet 1, and the external thread of the screw rod 901 is connected to a mounting plate 902, and the mounting plate 902 is fitted with the top inner wall and the inner walls on both sides of the cabinet 1. A limiting rod 903 is fixedly connected to the other side of the inner wall at one end of the cabinet 1, and the mounting plate 902 is slidably sleeved on the outside of the limiting rod 903. A motor is fixedly installed on the outer wall at one end of the cabinet 1, and the motor output shaft and one end of the screw rod 901 are coaxially fixed.

[0024] A plurality of mounting holes 2 are provided on the top outer wall of the cabinet 1 , and the edges of the tops and bottoms of the plurality of mounting holes 2 are rounded so that the edges of the mounting holes 2 will not scratch the movable wires.

[0025] A movable portion is reserved on the outside of the wire passing through the mounting hole 2, and the motor inside the protective cover 904 is started. The output end of the motor drives the screw rod 901 to rotate. Driven by the screw rod 901 and in cooperation with the limit rod 903, the mounting plate 902 will translate toward the outside along the limit rod 903, and the reserved end of the movable wire will enter the cabinet 1 to ensure that the movement of the mounting plate 902 will not be hindered.

[0026] like Figure 1As shown, a leakage protector 6 and a controller 7 (the controller 7 model is preferably CPM1A-10CDR-A-V1) are fixedly installed at one end of the inner wall at the bottom of the cabinet 1, and the leakage protector 6 is electrically connected to the inner wall of the cabinet 1 through a wire. A buzzer 8 is fixedly installed on the outer wall of one side of the cabinet 1, and the leakage protector 6 and the buzzer 8 are both electrically connected to the controller 7 through a wire, and a plurality of through holes are opened at the bottom of the inner wall at one end of the cabinet 1.

[0027] If an accidental leakage occurs, the current transmitted to the cabinet 1 will be detected by the leakage protector 6, and the monitoring signal will be transmitted to the controller 7. The controller 7 will control the buzzer 8 to start, and the buzzer 8 will sound an alarm, thereby reminding the staff to deal with it in time.

[0028] like Figure 2 and Figure 3 As shown, the outer wall at one end of the cabinet body 1 is rotatably connected to a cabinet door 4 through a hinge, a plastic plate 5 is fixedly installed on the outer wall on one side of the cabinet door 4, and the handle of the cabinet door 4 is also made of plastic material. The plastic plate 5 and the plastic handle can prevent leakage current from causing harm to maintenance personnel.

[0029] like Figure 1 and Figure 2 As shown, a reinforcement block 3 is fixedly connected to the bottom of the inner walls on both sides of the cabinet 1, one end of the screw rod 901 is rotatably connected to the outer wall of one end of one of the reinforcement blocks 3, and one end of the limit rod 903 is fixedly connected to the outer wall of one end of the other reinforcement block 3, which can increase the stability of the screw rod 901 and the limit rod 903.

[0030] like Figure 2 As shown, a protective cover 904 is fixedly installed on the outer wall of one end of the cabinet 1. The protective cover 904 surrounds the outside of the motor and can protect the motor from damage caused by the external environment.

[0031] like Figure 1 As shown, the top inner wall of the mounting plate 902 is located above the leakage protector 6 and the controller 7 , so that the movement of the mounting plate 902 will not be hindered by the leakage protector 6 and the controller 7 .

[0032] The utility model provides an insulating switch cabinet with a leakage alarm function, and the specific working principle is as follows:

[0033] When the device is working, the switches on the mounting plate 902 are connected by wires, and a movable part is reserved outside the wire passing through the mounting hole 2. With the increase of the use time, if an accidental leakage occurs, the current transmitted to the cabinet 1 will be detected by the leakage protector 6, and the monitoring signal will be transmitted to the controller 7. The controller 7 will control the buzzer 8 to start, and the buzzer 8 will sound an alarm, so as to remind the staff to deal with it in time. When maintenance is required, the cabinet door 4 is opened first, and the plastic plate 5 outside the cabinet door 4 can prevent the leakage current from causing harm to the maintenance personnel. Then the motor inside the protective cover 904 is started, and the output end of the motor drives the screw rod 901 to rotate. The mounting plate 902 will be translated toward the outside along the limit rod 903 under the drive of the screw rod 901 and the cooperation of the limit rod 903, and the reserved end of the movable wire will enter the cabinet 1 to ensure that the movement of the mounting plate 902 will not be hindered.
