Description

A kind of electrical control interlock
Technical field
The present invention relates to electrical control equipment, particularly relate to a kind of electrical control interlock.
Background technology
That is: 1 require five anti-interlockings in current power supply process, prevent by mistake point, close circuit breaker; 2, prevent on-load from dividing, close isolating switch; 3, band cable address (conjunction) earth connection (earthed switch) is prevented; 4, band ground wire power transmission is prevented; 5, mistakenly entering charged chamber is prevented.But " five anti-interlockings " in actual use, needed for power reguirements annoyings electrical complete equipment manufacturer always.
In existing technology, mainly there is following problem:
Existing interlocking loose mail is installed extremely complicated, often needs masterful technique workman that little for kind more than 40 parts in-site installation is completed.
Debug difficulties, operating state is extremely unstable, causes some machine components to loosen, is out of shape, finally cause controller switching equipment to run particularly by scene transport, site operation etc.
Mechanism operation illustrates unintelligible, easily causes misoperation, seriously can cause blast and casualties.
Isolating switch axle sleeve procedure is complicated, needs experienced workman debug the installation site of axle sleeve and isolator operation axle and will on-the-spot hole during installation, and is difficult to guarantee that operating axis rotation makes the depression distance of guiding depression bar meet the requirements.
Whole mechanism loose mail is by two block operations panels, axle sleeve, depression bar, connecting rod, direction board, holder, spring, catch, slip copper sheathing, in addition various connection finding, in-site installation is extremely complicated, also certain sequencing is had, and be easy to cause error in Installation and Debugging process, to such an extent as to operate not in place, have a strong impact on the stability of equipment.
Summary of the invention
Technical problem to be solved by this invention is to provide the electrical control interlock for realizing five anti-interlockings that a kind of structure is simple, integrated level is high.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of electrical control interlock, comprise earthed switch operating axis, isolator operation axle and housing, each operating axis is all that one end is connected with the bonnet of described housing, the other end is provided with convex axle, the opposite face of described housing and described bonnet is provided with control panel, each operating axis lower end is equipped with cam, each lower cam end is all connected with the direction board being arranged on control panel outer surface accordingly by transmission mechanism, and described direction board comprises earthed switch direction board and isolating switch direction board;
When rotating earthed switch operating axis and making cam disposed thereon rotate to minimum point, earthed switch direction board moves downwardly to extreme position under the drive of the first transmission mechanism, when rotary isolation switch operating axis makes cam disposed thereon rotate to minimum point, isolating switch direction board moves downwardly to extreme position under the drive of the second transmission mechanism;
Described control panel is provided with two corresponding with described earthed switch operating axis and isolator operation axle respectively earthed switch handle holes and isolator operation hole, slide damper is provided with inside described control panel, described slide damper by slide block in isolator operation hole and earthed switch handle hole at least one, when earthed switch handle hole or isolator operation hole are not blocked, the convex axle that operating grip can be used corresponding connects, thus rotates corresponding earthed switch operating axis or isolator operation axle;
