Description

Technical Field

[0001] The utility model belongs to the technical field related to switch cabinets, and in particular relates to a GCS type low-voltage switch cabinet. Background Art

[0002] GCS low-voltage switchgear is a low-voltage withdrawable switchgear widely used in industrial and civil building power distribution systems. The main structural features of GCS low-voltage switchgear include the use of a high-strength main frame, high strength and good pre-treatment processability. The internal functional divisions of the cabinet are clear, divided into functional unit rooms, busbar rooms and cable rooms, and each functional unit is relatively independent, but it still has the following disadvantages in actual use:

[0003] During the operation of the GCS low-voltage switchgear, the electrical switches therein will generate heat, so it is necessary to exhaust the air through the blowing equipment. During operation, the switchgear is installed separately through iron sheets, and the heat transfer between the iron sheets is fast, which makes it inconvenient to control the different heat dissipation efficiencies between different drawers of the switchgear;

[0004] When the GCS type low-voltage switchgear is working, during long-term operation, the internal electrical switch structure is relatively complex. When a fault occurs, the temperature in a single drawer will rise rapidly. At this time, it is not convenient to locate the fault position and respond quickly for maintenance. Utility Model Content

Support bars 102 are fixed on both side walls of the outer box body 1 at the bottom of each installation box 2. The installation box 2 is supported in the outer box body 1 by the support bars 102. A plurality of installation rails 3 are fixed in the lower part of the installation box 2. The electrical switch is installed thereon through the installation rails 3, so that the electrical switch is installed in the installation box 2. An air inlet pipe 205 is fixedly connected to the center of the front side of the installation box 2.

The outer exhaust holes 101 on the outer box body 1 correspond one-to-one to the inner exhaust holes 201 on all the installation boxes 2. The heat-dissipating air enters the installation box 2 through the air inlet pipe 205. After passing through the electrical switch, the heat-dissipated air is transported to the outer exhaust holes 101 through the inner exhaust holes 201 and is discharged through the outer exhaust holes 101.

[0028] Furthermore, a fixing bar 302 is fixed to the bottom of each mounting rail 3 along a center line parallel to the long side, and the bottom of the fixing bar 302 is fixed to the inner bottom of the mounting box 2. Each mounting rail 3 has equidistant mounting screw holes 301 vertically opened along the length direction at the top. The mounting rail 3 is supported at the bottom of the mounting box 2 by the fixing bar 302, thereby increasing the supporting stability of the mounting rail 3 and providing installation for the electrical switch through the mounting screw holes 301.

[0029] Furthermore, a heat insulation board 209 is fixed to the bottom of the installation box 2, and the heat insulation board 209 is arranged between two support bars 102 at the same height in the outer box body 1. The upper and lower installation boxes 2 are insulated by the heat insulation board 209, so that there is less interference between the upper and lower adjacent installation boxes 2.

[0030] The operation process of this embodiment is as follows: when installing, first pull out the installation box 2 in the outer box body 1, put the electrical switch to be installed on the installation track 3, and install it through the installation screws. After installation, reset the installation box 2 in the outer box body 1 and start working. During operation, air is transported to the installation box 2 through the air inlet pipe 205, and after the electrical switch in the installation box 2 is cooled, the heat-dissipated air is transported to the outer exhaust hole 101 through the inner exhaust hole 201, and is discharged through the outer exhaust hole 101 on the outer box body 1. The upper and lower installation boxes 2 are insulated by the insulation board 209, so that there is less interference between the upper and lower adjacent installation boxes 2.

[0033] Furthermore, an alarm 204 is fixedly connected to a corner on the upper front side of each installation box 2, and a thermal switch 203 is fixed to one side of the inner wall of each installation box 2. When the electrical switch in the installation box 2 is abnormally heated or a safety accident such as a fire occurs, the thermal switch 203 is opened. After the thermal switch 203 is opened, the alarm 204 is activated to sound an alarm.

[0034] The operation process of this embodiment is as follows: during operation, after the electrical switch is installed in the installation box 2, the wires on the electrical switch are passed through the wire tube 207 into the soft sleeve 208, and then passed out through the soft sleeve 208. The wires are sealed by the soft sleeve 208, and then the installation box 2 is pushed into the outer box body 1 by pushing the heat-insulating handle 206.
