Description

A drawer type switch cabinet

technical field

The utility model relates to a switch cabinet, in particular to a drawer type switch cabinet.

Background technique

At present, in the low-voltage control system of electric power supply, it is necessary to realize the mixing of the control loops of the three-pole switch drawer and the four-pole switch drawer in the same switch cabinet. The existing switch cabinet includes a cabinet body, which is provided with a busbar. A pole, B pole, C pole and N pole are four poles. The cabinet body is also equipped with a static plug at the incoming line end and a static plug at the outgoing line end that are plugged and electrically connected with the three-pole switch drawer and the four-pole switch drawer respectively. The plug-in includes a first-level static plug-in and a second-level static plug-in. The static plug-ins at the incoming line end of the existing switchgear are all four-pole incoming line static plug-ins including four plug-in terminals of A pole, B pole, C pole and N pole. , the static inserts at each incoming line end are electrically connected to the corresponding poles of the bus bar, and the switchgear is also equipped with an incoming line cover and a vertical bus bar clamp. It is a four-pole busbar clamp with four plug-in terminals. The outlet end static plug for plugging and electrical connection with the three-pole switch drawer in the existing switch cabinet is a three-pole outlet end static plug that does not include the N pole, and is used for connecting with the three-pole switch drawer. The four-pole switch drawer is plugged with a static plug at the outlet end of the electric connection, which is a static plug at the four-pole outlet end.

In the existing switchgear, since all the static inserts, vertical busbar clips and wire inlet covers of the incoming wires are set as four poles, and the N pole is not set on the three-pole switch drawer, it corresponds to the three-pole switch drawer when in use. The N-pole of the plug-in terminal static plug-in is idle, resulting in waste of raw materials and copper bars; the static plug-in plug-in of the existing switch cabinet for plugging with the three-pole switch drawer is a four-pole static plug-in terminal , because the three-pole switch tap on the wall of the four-pole inlet terminal static plug has one more N-pole connector, which is easy to cause misconnection; The static plug-in is a three-pole outlet terminal static plug-in, which is confusing during actual deployment and installation, prolonging the production and installation cycle.
