Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of switch cabinets, and more specifically, to a drawer-type switch cabinet. Background Art
[0002] At present, the drawer-type switch cabinet is made of steel plates to form a closed shell, and the electrical components of the incoming and outgoing line circuits are all installed in the drawable drawers, constituting a functional unit that can complete a certain type of power supply task.
[0003] However, usually in the use of the drawer cabinet, the conventional form of the drawer plug-in is to install the main circuit moving plug and the primary incoming line cover on the incoming line side of the drawer cabinet, and install the main circuit moving and static plugs and the secondary moving and static plugs on the outgoing line side. The vertical row is connected to the incoming line side behind the drawer, and then lapped with the horizontal row on the top of the cabinet body. Sometimes in projects, a small-capacity power system will be encountered, such as a molded case circuit breaker with an incoming line breaker of 630A. At this time, there are two options. One is to make a separate 630A incoming line cabinet, which not only increases the cost, but also may lead to waste of space and complexity of management; the other is to make the 630A incoming line circuit breaker into a drawer circuit. Although the second method has the advantages of convenient maintenance, economy and applicability, this solution requires connecting the incoming line cable to the plug-in on the outgoing line side, which will cause the molded case circuit breaker to have an inverted incoming line. The occurrence of an inverted incoming line in the molded case circuit breaker may cause unstable current and even lead to electrical accidents.
[0004] Therefore, how to provide a drawer-type switch cabinet that can solve the above problems is an urgent problem for those skilled in the art. Summary of the Invention
[0005] In view of this, the utility model provides a drawer-type switch cabinet, which solves the problem of the inverted incoming line of the molded case circuit breaker, ensures the normal operation of the power system, and greatly reduces the cost.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A drawer-type switch cabinet, comprising:
[0008] A drawer cabinet, which has an incoming line side and an outgoing line side;
[0009] The first main circuit static plug, which is arranged on the incoming line side;
[0010] The first main circuit moving plug, which is arranged on the incoming line side;
[0011] The second main circuit static plug, which is connected to the outgoing line side through a connecting device;
[0012] The second moving plug-in unit of the main circuit, and the second moving plug-in unit of the main circuit is connected to the outgoing line side through a connecting device.
[0013] Preferably, the connecting device includes:
[0014] A vertical wiring harness, which is arranged inside the drawer cabinet;
[0015] A transfer wiring harness, which is arranged inside the drawer cabinet and has its input side connected to the vertical wiring harness and its output side connected to the second static plug-in unit of the main circuit.
[0016] Preferably, the connecting device further includes:
[0017] A secondary static plug-in, which is arranged on the transfer wiring harness.
[0018] Preferably, it further includes:
[0019] A circuit breaker mounting plate, which is arranged inside the drawer cabinet.
[0020] Preferably, it further includes:
[0021] A circuit breaker, which is connected to the circuit breaker mounting plate.
[0022] Preferably, the second static plug-in unit of the main circuit is provided with a static plug-in wire transparent cover.
[0023] Preferably, it further includes:
[0024] A drawer operating mechanism, which is arranged inside the drawer cabinet.
[0025] Through the above technical solutions, compared with the prior art, the present utility model discloses a drawer-type switchgear cabinet. By arranging the incoming line side at the bottom of the drawer cabinet and making the static plug-in unit of the main circuit incoming line side have the same model as the static plug-in unit of the main circuit of the outgoing line side, that is, making the incoming drawer circuit have a double plug-in at the back. The vertical wiring harness does not need to extend to all drawer circuits, only needs to reach the drawer above the incoming drawer circuit. A section of transfer wiring harness is made on the static plug-in unit of the main circuit on the incoming line side of the drawer, and the power incoming line cable is connected to this section of transfer wiring harness. Through the above settings, the incoming line mode of the incoming drawer circuit can be changed, which not only solves the problem of reverse incoming line of the molded case circuit breaker and ensures the normal operation of the power system, but also greatly reduces the cost.
