The utility model content
The purpose of this utility model is to provide a kind of can avoid the human operational error, safe and reliable full-automatic interlock.
For achieving the above object, the technical solution of the utility model is as follows:
The full-automatic interlock of a kind of parts removed of adjacent switch cabinet, it is characterized in that, comprise the main interlocking that is arranged in the main interlocking switch cabinet can remove parts one side main interlocking device and be arranged on by in the interlocking switch cabinet by the interlocking can remove parts one side by interlocking device, described main interlocking device and be separately positioned on main interlocking switch cabinet by interlocking gear and by the attachment side of interlocking switch cabinet, described main interlocking device and being communicated with one another by blocking lever between the interlocking device, the both sides of described blocking lever are provided with positioning sleeve, and the near main interlocking device side of described latch lever is provided with back-moving spring.
Described main interlocking device comprises that the main interlocking that is fixed in the main interlocking switch cabinet can remove the briquetting of parts one side, and the top of described briquetting slidably contacts with an end of described blocking lever.
The top of described briquetting is low wide and up narrow inclined-plane.
The described block and the location hole that is arranged on certain position on the block that can be removed parts one side by interlocking that is fixed on by in the interlocking switch cabinet that comprised by interlocking device.
Described location hole is arranged in the described position of the other end correspondence of described blocking lever during by can being removed parts and be in the service position by interlocking of interlocking switch cabinet.
During concrete the application, interlocking will be led and the parts propelling can be removed, being contained in main interlocking can remove the briquetting of parts side and press blocking lever and move, in the time can being removed parts in the service position by interlocking, blocking lever just in time enters to be decided in the hole, making by interlocking can remove parts and can not arbitrarily be spurred, and can be removed parts not in normal operation position when interlocking the time, can be removed the blocking lever that the block of parts side is moved by interlocking and block, making and to be removed parts by interlocking and can not move forward.
The utility model is simple in structure, and is easy to operate, and automatic interlock has guaranteed the reliability of interlocking, can avoid effectively that human factor causes operate miss, very help switchgear house operating personnel operation.
