Description
Technical Field
The utility model relates to a low pressure electrical control equipment, in particular to be used for drawer type switch cabinet interlocking device to go up examines latch mechanism.
Background
The drawer type switch cabinet is a functional unit capable of completing a certain power supply task, a steel plate is generally adopted to make a closed shell, a main switch is arranged in the closed shell, and the main switch is provided with a wire inlet end electrically connected with a live bus and a wire outlet end electrically connected with an external electrical appliance element. When the drawer type switch cabinet breaks down and needs to be overhauled, the drawer type switch cabinet can be directly taken out from the inside of the switch cabinet frame body for overhauling, and after overhauling is finished, the drawer type switch cabinet is pushed into the inside of the switch cabinet frame body, so that the operation is very convenient. The drawer type switch cabinet is widely applied to the field of low-voltage electrical appliance control equipment.
When the drawer type switch cabinet is in a normal working state, the electric energy input end and the electric energy output end of the main switch are in an electric communication position, and an external electrical component is electrically connected with the electrified bus through the main switch, so that the drawer type switch cabinet is drawn out at will to easily cause danger. In order to ensure safety, prior art drawer type switch cabinets are generally provided with an interlocking mechanism. The interlocking mechanism can lock the drawer type switch cabinet on the switch cabinet frame body when the drawer type switch cabinet is in a working state, so that the drawer type switch cabinet is prevented from being drawn out randomly; when the drawer type switch cabinet is in a power-off state, the locking state of the drawer type switch cabinet and the switch cabinet frame body is released, so that the drawer type switch cabinet can be pulled out from the switch cabinet frame body for maintenance or inspection.
Because the main switch is installed inside the drawer type switch cabinet, when the drawer type switch cabinet is overhauled, the interlocking mechanism needs to be operated firstly to release the locking state between the drawer type switch cabinet and the switch cabinet frame body, then the main switch is operated manually to break the electric connection between the electric appliance element and the bus, and then the drawer type switch cabinet is pulled out from the drawer type switch cabinet frame body for overhauling. Because the manual operation of the main switch is inconvenient and easy to cause electric shock danger after the locking state between the drawer type switch cabinet and the drawer cabinet frame body is released, people generally link the main switch and the interlocking mechanism at present, when the interlocking mechanism is operated to release the locking state between the drawer type switch cabinet and the switch cabinet frame body, the main switch is linked to disconnect the electric connection between the bus and the electric appliance element, and when the interlocking mechanism is operated to lock the drawer type switch cabinet on the switch cabinet frame body, the main switch is linked to connect the electric connection between the bus and the electric appliance element. Because the main switch has the function of automatic circuit breaking protection, the interlocking mechanism and the main switch are linked, and simultaneously, the tripping action when the main switch starts the automatic circuit breaking protection is prevented from being blocked.
Patent document CN201510024951.7, a "interlock mechanism and a drawer type switch cabinet with the interlock mechanism", discloses an interlock mechanism, which includes a rotating transmission member, one end of which is fixedly connected with a main switch inside the drawer type switch cabinet, and the other end of which is provided with an operation part; the rotating transmission part is provided with a first locking structure, the switch cabinet frame body used for supporting the drawer type switch cabinet is provided with a second locking structure, and the first locking structure can be matched with the second locking structure to lock or unlock along with the rotation of the rotating transmission part. According to the interlocking mechanism, no matter the main switch drives the first locking structure to rotate through the rotating transmission part or uses an external force to operate the operation part and drive the first locking structure to act through the rotating action part, the change between the locking state and the unlocking state between the drawer type switch cabinet and the switch cabinet frame body can be realized only by driving the rotating transmission part and the first locking structure to rotate, the driving resistance is small, the interlocking mechanism can be suitable for the main switch with the rotating action, the tripping action cannot be blocked, and the safety performance is high.
In the actual use process, because this interlocking device's drive resistance is little, when staff's maloperation or idle person etc. (children etc.) are close to the switch board and touch or twist the operating portion soon, not only can make corresponding consumer outage, have great potential safety hazard more.
