Abstract
The utility model relates to the technical field of inlet wire switch cabinet and measuring cabinet, and especially relates to a mechanical interlocking mechanism between a breaker handcart and a measuring cabinet handcart in the inlet wire switch cabinet and the measuring cabinet. The mechanical interlocking mechanism mainly comprises the measuring cabinet handcart, the breaker handcart, a right program lock, a left program lock, and a program pin. The right program lock is disposed on a top of the measuring cabinet handcart in the measuring cabinet handcart. A left side of the right program lock is provided with the program pin. A cabinet wall on a left side of the measuring cabinet is provided with a blind hole corresponding to a position of the program lock. The inlet wire cabinet is connected on a left side of the measuring cabinet. The left program lock is disposed on a top of the breaker handcart in the inlet wire cabinet. The mechanical interlocking mechanism is advantaged in that using the interlocking mechanism, the measuring handcart is prevented from being operated with load and the interlocking mechanism ensures to switch on after the measuring handcart is completely in position. The structure is scientific and practical, operation is convenient and fast, effect is very obvious, so that operation security in engineering is ensured, rigid operation flow requirements prevent accidents from occurring in operation, and operation risk is reduced.
Description
Technical field
The utility model relates to incoming line switch cabinet and metering cabinet technical field, relates in particular in the incoming line switch cabinet and the circuit breaker cart in the metering cabinet, the mechanical interlock mechanism between the metering cabinet handcart.
Background technology
In existing different switch cubicles, there is not 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 as required interim installation, there are very large hidden danger in quality and security reliability, and this type of engineering mainly is to be used in the terminal use, and its operating personnel's technical skills residual error is uneven, the site environment more complicated is so exist very large potential safety hazard.
The applicant has the disappearance that sees mechanical interlock mechanism in the above-mentioned known switch cubicle, adheres to research and innovation, excelsior spirit, utilizes professional eye and professional knowledge, proposes a simple and practical solution, so propose the application of this case.
Summary of the invention
The purpose of this utility model is to solve the problem of present metering handcart chassis interlocking electromagnet quality and the very large hidden danger of security reliability existence, and the mechanical interlock mechanism of a kind of circuit breaker cart and metering cabinet handcart is provided.
For achieving the above object, the utility model adopts following technical scheme: mainly comprise metering cabinet handcart, circuit breaker cart, right procedure lock, left procedure lock, the program lock pin, the metering cabinet handcart top of placing in metering cabinet is provided with right procedure lock, right procedure lock left side is with the program lock pin, and it is corresponding with program lock pin position to have blind hole at the left side of metering cabinet cabinet wall; The left side of metering cabinet has connected incoming line cabinet, and the circuit breaker cart top of placing in the 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 the symmetric position relation, and share a key.
The utility model has the advantage of: adopt novel interlocking device, effectively prevented the operation of metering handcart on-load and guaranteed that metering handcart could close a floodgate after fully in place, scientific structure is practical, convenient to operation, action effect is fairly obvious, guaranteed the safety in the operation engineering, rigid operating process requires to have avoided the operative employee security incident to occur, has reduced operational risk.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
See also shown in Figure 1, the utility model comprises 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 are with program lock pin 7, and it is corresponding with program lock pin 7 positions to have blind hole 6 at the left side of metering cabinet 1 cabinet wall.
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 same setting program lock pin 7 in left procedure lock 8 right sides, it is corresponding with program lock pin 7 to be provided with equally blind hole 6 at the right cabinet wall of incoming line cabinet 2, left procedure lock 8 is the symmetric position relation with right procedure lock 5, and shares a key.
When the utility model is implemented, right procedure lock 5 and left procedure lock 8 have been installed and fixed at metering cabinet handcart 3 and circuit breaker cart 4 panels first, when sending electricity, metering cabinet handcart 3 is shifted onto the service position, right procedure lock 5 keys to anticlockwise, program lock pin 7 passes circular hole 6, and to stop metering cabinet handcart 3 outwards mobile, extracts simultaneously key; Key is injected the left procedure lock 8 of the circuit breaker cart 4 in the 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 left turn, 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, more than diagram is the utility model preferred embodiments only, is not to limit the scope of application of the present utility model with this, so, everyly make equivalent change in the utility model principle and all should be included in the protection range of the present utility model.
