Problems solved by technology

[0005] However, the models of MNS, GCS and GCK cabinets are not uniform in profile modulus. MNS and GCK are 25mm, and GCS is 20mm. The difference in modulus brings structural differences. For the same 1-unit 8E drawer, MNS and GCK are 200mm high, while GCS is 160mm high, etc. The difference makes the low-voltage switchgear further complicated, so that the designer needs to design and install the same component and different cabinet types according to different standards, which brings a lot of inconvenience to the design and installation

Embodiment 1

[0030] Such as figure 2 As shown, the drawers 1031 of the functional unit room 103 all use drawers with a height modulus of 8E3101, and are a combination of 1 unit I and 1 / 2 II unit drawers.

Embodiment 2

[0032] Such as image 3 As shown, the drawer 1031 of the functional unit room 103 uses a combination of drawers whose height modulus is 10E 3102, 20E 3103 and 30E 3104, and is a combination of 1 unit I, 1 / 2 unit II and 1 / 4 unit III drawers.

Embodiment 3

[0034] Such as Figure 4 , the drawer 1031 of the functional unit room 103 uses a combination of drawers with a height modulus of 8E 3101 and 10E 3102, and is a 1 unit I drawer.

[0035] Through the above three implementation modes, it can be seen that the switchgear provided by the present invention integrates the advantages of GCK, GCS, and MNS, and has strong versatility. The coexistence of drawer cabinets with different unit heights can be realized, and the combination of different requirements can be realized, with flexibility and strong applicability.

[0036] Such as Figure 5 , The drawer in the switch cabinet provided by the present invention is provided with a control handle 10 and a mechanical interlocking device. The mechanical interlocking device is provided with five operating positions of connection 1, test 2, separation 3, breaking 4 and movement 5, which are marked on the outer periphery of the control handle 10 and controlled by the control handle 10. Ther...

Abstract

The present invention provides a switch cabinet, comprising a cabinet body, wherein the cabinet body comprises a frame, peripheral panels and internal separator plates, the cabinet body is divided into a bus-bar chamber, a cable chamber, a function unit chamber and a control circuit chamber through the internal separator plates; the frame adopts a sectional material with the module of E=20mm; the bus-bar chamber is arranged at the rear part of the cabinet body, the cable chamber is arranged at the right side of the front side of the cabinet body, the function unit chamber is arranged at the left side of the front side of the cabinet body, and the control circuit chamber is arranged at the upper part of the front side of the cabinet body; the function unit chamber is provided with drawers, the adjacent drawers are completely separated through a movable drawer separator plate, the movable drawer separator plate is inserted into a drawer separator plate slot; the drawers can be 1-unit drawers, 1 / 2-unit drawers or 1 / 4-unit drawers, the module of the height of the drawer can be any one or any combination of 8E, 10E, 20E or 30E; and the drawers are provided with a mechanical interlocking device. The switch cabinet provided by the present invention can achieve coexistence of drawers with different unit heights, thus applicability is good, and protection grade is high.

Description

technical field [0001] The invention relates to a low-voltage switchgear, in particular to a switchgear with flexible combination, safety and reliability. Background technique [0002] At present, there are various cabinet models of GGD, MNS, GCS, and GCK for low-voltage switchgear, among which GGD is a fixed type switchgear, while GCK, GCS, and MNS are all drawer type switchgears. [0003] GGD type AC low-voltage switchgear: This switchgear has the advantages of reasonable structure, convenient installation and maintenance, good protection performance, high breaking capacity, large capacity, strong breaking capacity, strong dynamic stability, and wide applicability of electrical solutions. However, it At the same time, it also has the disadvantages of fewer circuits, no arbitrary combination of units, and a large footprint. [0004] The space utilization rate of the drawer type switchgear is high, which solves the disadvantage of large floor space. [0005] However, the m...
