Abstract
The invention relates to the technical field of inlet wire switch cabinets and measuring cabinets, in particular to a mechanical interlocking mechanism of a circuit breaker handcart and a measuring cabinet handcart in an inlet wire switch cabinet and a measuring cabinet. The mechanical interlocking mechanism mainly comprises the measuring cabinet handcart, the circuit breaker handcart, a right program lock, a left program lock, and a program lock pin. The right program lock is arranged on the top of the measuring cabinet handcart positioned in the measuring cabinet. The left side of the right program lock is provided with the program lock pin. The cabinet wall on the left side of the measuring cabinet is provided with a blind hole corresponding to the program lock pin in position. The inlet wire cabinet is connected to the left side of the measuring cabinet. The left program lock is arranged on the top of the circuit breaker handcart positioned in the inlet wire cabinet. The mechanical interlocking mechanism has the advantages that with the adoption of the interlocking mechanism, the measuring handcart is prevented from being operated with load, switching on is achieved only after the measuring handcart is completely in position, the structure is scientific and practical, operation is convenient and fast, the effect is very obvious, operation security in engineering is ensured, rigid operation process requirements prevent accidents from occurring in operators, and operation risks are reduced.
Description
Technical field
The present invention relates to incoming line switch cabinet and metering cabinet technical field, relate in particular to the circuit breaker cart in incoming line switch cabinet and in metering cabinet, the mechanical interlock mechanism between metering cabinet handcart.
Background technology
In existing different switch cubicles, there is no at present special-purpose mechanical interlock mechanism, and metering cabinet handcart does not have arc-control device, can not operate by on-load, so common practice all adopts electrical interlock, but because metering handcart chassis interlocking electromagnet is to install as required temporarily, there is very large hidden danger in quality and security reliability, and this type of engineering is to be mainly used in terminal use, and its operating personnel's technical skills residual error is uneven,, so there is very large potential safety hazard in site environment more complicated.
The applicant has the disappearance that sees mechanical interlock mechanism in above-mentioned known switch cubicle, adheres to research and innovation, excelsior spirit, utilizes professional eye and professional knowledge, proposes a simple and practical solution, therefore propose the application of this case.
Summary of the invention
The object of the invention is to solve the problem of current metering handcart chassis interlocking electromagnet quality and the very large hidden danger of security reliability existence, the mechanical interlock mechanism of a kind of circuit breaker cart and metering cabinet handcart is provided.
For achieving the above object, the present invention adopts following technical scheme: mainly comprise metering cabinet handcart, circuit breaker cart, right procedure lock, left procedure lock, program lock pin, the metering cabinet handcart top of placing in metering cabinet is provided with right procedure lock, right procedure lock left side, with program lock pin, has blind hole at the left side of metering cabinet cabinet wall corresponding with program lock pin position; The left side of metering cabinet has connected incoming line cabinet, and the circuit breaker cart top of placing in incoming line cabinet is provided with left procedure lock, the same setting program lock pin in left procedure lock right side.
Described left procedure lock and right procedure lock are symmetric position relation, and share a key.
The invention has the advantages that: adopt novel interlocking device, effectively prevented the operation of metering handcart on-load and guaranteed that metering handcart could close a floodgate after completely in place, scientific structure is practical, convenient to operation, action effect is fairly obvious, guaranteed the safety in operation engineering, rigid operating process requires to have avoided operative employee to occur security incident, has reduced operational risk.
accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present invention.
embodiment:
Below in conjunction with accompanying drawing, the present invention is further described:
Refer to shown in Fig. 1, the present invention includes metering cabinet handcart 3, circuit breaker cart 4, right procedure lock 5, left procedure lock 8, program lock pin 7, is provided with right procedure lock 5 at metering cabinet handcart 3 tops of metering cabinet 1 interior placement, right procedure lock 5 left sides, with program lock pin 7, have blind hole 6 at the left side of metering cabinet 1 cabinet wall corresponding with program lock pin 7 positions.
The left side of metering cabinet 1 has connected incoming line cabinet 2, circuit breaker cart 4 tops of incoming line cabinet 2 interior placements are provided with left procedure lock 8, the left procedure lock 8 same setting program lock pins 7 in right side, at the right cabinet wall of incoming line cabinet 2, be provided with equally blind hole 6 corresponding with program lock pin 7, left procedure lock 8 is symmetric position relation with right procedure lock 5, and shares a key.
During the invention process, first on metering cabinet handcart 3 and circuit breaker cart 4 panels, install and fix right procedure lock 5 and left procedure lock 8, during power transmission, metering cabinet handcart 3 is shifted onto to service position, right procedure lock 5 keys to anticlockwise, program lock pin 7 stops metering cabinet handcart 3 through circular hole 6 and outwards moves, and extracts key simultaneously; Key is injected to the left procedure lock 8 of the circuit breaker cart 4 in incoming line cabinet 2, then to right rotation, program lock pin 7 locks are gone back, circuit breaker cart 4 service position that can make smooth advances.
During power failure, circuit breaker cart 4 is moved to test position, left procedure lock 8 keys are selected and turned left, pin the movement of circuit breaker cart 4, extract key, key is inserted on the right procedure lock 5 of metering cabinet handcart 3, to right rotation, lock backhaul order lock pin 7, can continue to operate metering cabinet handcart 3.
Certainly, above diagram, only for better embodiment of the present invention, not limits the scope of application of the present invention with this, therefore, everyly in the principle of the invention, make equivalent change and all should be included in protection scope of the present invention.
