detailed description

The present application will be described in further detail below in conjunction with accompanying drawings 1-3.

The embodiment of the application discloses a leakage protector for an electrical control cabinet. Referring to Figures 1-3, a leakage protector for an electrical control cabinet includes a leakage protector 1 and a mounting base 2, one side of the leakage protector 1 is provided with a mounting base 2, and both sides of the mounting base 2 are fixedly installed with mounting brackets. Ear 4, one side of the mounting ear 4 is fixed with a mounting groove 5 near the mounting seat 2, and the top of the inner cavity of the mounting groove 5 is movably installed with a disassembly key 6;

The disassembly key 6 includes a pull rod 61, and the pull rod 61 moves through the inside of the installation ear 4, and one end of the pull rod 61 is fixedly connected with a wedge block 62, and the wedge block 62 is located in the inner cavity of the installation groove 5, and the pull rod 61 is located in the installation ear One side of 4 is fixedly installed with a limiting plate 63, and a spring 64 is installed on the outside of the pull rod 61. The pull rod 61 is located at one end of the spring 64 and is provided with a limit frame 65, and the two ends of the limit frame 65 are fixed on the mounting ear 4. side.

By setting the disassembly key 6 and the matching installation ear 4 and installation groove 5, the earth leakage protector 1 needs to use auxiliary tools when it is installed in the control box for the first time. 6 can be disassembled and assembled with one key, so that the earth leakage protector 1 is disassembled conveniently and saves time.

As shown in Figure 2, the inner side of the mounting ear 4 is penetrated with a heat dissipation window 7, and the heat dissipation window 7 is located on both sides of the earth leakage protector 1, and a radiator 8 is fixedly installed on one side of the heat dissipation window 7, and the radiator 8 is located on the installation side. side of ear 4.

Because the temperature of the inner cavity of the electrical control box is higher than that of the ordinary environment, the radiator 8 increases the air flow on both sides of the earth leakage protector 1 to increase the heat dissipation effect.

As shown in FIG. 1 , mounting plates 3 are fixedly installed on both sides of the earth leakage protector 1 , and the mounting plates 3 are located in the inner cavity of the mounting groove 5 .

The installation plate 3 is used for the installation and cooperation between the earth leakage protector 1 and the installation ear 4 .
