Embodiment Construction

[0020] Embodiment of the drawer unit of the low-voltage drawer switchgear, such as Figure 1-2 As shown, the low-voltage drawer switch includes a cabinet and a drawer unit. The structure of the cabinet is in the prior art, so it is not shown in the drawings, and will not be described in detail here.

[0021] The drawer unit includes a circuit breaker and an operating mechanism of the circuit breaker. The circuit breaker is a molded case circuit breaker. In this embodiment, there are two circuit breakers, and the two circuit breakers are respectively installed on both sides of the mounting frame.

[0022] The operating mechanism is used to realize the switching operation of the circuit breaker. The operating mechanism includes a mounting frame 11 on which an input shaft 12 is rotatably mounted. The input shaft 12 is located between two circuit breakers. In addition, the input shaft 12 is also provided with a top screw hole on the hole wall of the jack. When in use, the correspo...

Abstract

The invention relates to the field of an electrical device, in particular to a low-voltage drawer-type switch cabinet, a drawer unit and an operating mechanism. The low-voltage drawer-type switch cabinet comprises a cabinet body and the drawer unit, the drawer unit comprises more than two breakers and the operating mechanism of the breakers, the operating mechanism comprises an installation frame, input shafts and output shafts are rotatably assembled on the installation frame, the output shafts are in correspondence to the input shafts and used for driving the breakers to cut off, and the input shafts are arranged parallel to the output shafts and are in transmission connection with the output shafts via corresponding transmission mechanisms. During use, a plurality of breakers can be simultaneously operated via the input shafts, so that on-off operation of a plurality of loops can be achieved. Therefore, with the adoption of the low-voltage drawer-type switch cabinet, the problem that more than two loops cannot be simultaneously cut off by means of the drawer unit in the traditional drawer-type switch cabinet is solved.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a low-voltage drawer switch cabinet, a drawer unit and an operating mechanism. Background technique [0002] At present, in the low-voltage power distribution industry, drawer-type switch cabinets are often used to realize the connection of multiple lines. The drawer-type switch cabinets use a closed shell, and the electrical components of the incoming and outgoing circuit circuits are fastened and installed in drawers. A drawer unit that performs a certain type of power supply task. When a drawer unit breaks down, the drawer can be pulled out of the switchgear and moved outside for troubleshooting without the need to cut off the mains. At the same time, the drawer unit can also seal the fault inside the drawer unit without affecting the normal operation of other drawer units. Drawer-type switchgear is widely used for its reliability, safety, interchangeability and other adva...
