Abstract
The utility model relates to a ring network cabinet, which comprises a cabinet body, an isolating switch positioned above the cabinet body, a vacuum circuit breaker positioned below the isolating switch and provided with a linkage device, and an isolating switch operating handle connected with the isolating switch and provided with a position limiting mechanism. An interlocking device is arranged between the isolating switch and the vacuum circuit breaker, one end of the device is connected with the isolating switch, and the other end of the device is connected with the position limiting mechanism of the isolating switch operating handle. The ring network cabinet provided by the utility model has simple structure and reliable function, and is convenient for usage and installation. The operating handle is limited during operation process through the interlocking device, so as to realize irreversible sequence of operations and avoid accidents caused by errors in the sequence of operations.
Description
Technical field:
The utility model relates to the control appliance that uses in a kind of electrical system, particularly a kind of ring main unit.
Background technology:
Ring main unit has played the function of branch, segmentation and contact in distribution system, therefore obtained using widely in the cable net transformation of ground, city.Ring main unit is by cabinet and be arranged at elements such as isolating switch in the cabinet, vacuum circuit-breaker summation current transformer and constitute.The power supply copper busbar on cabinet top and isolating switch, vacuum circuit-breaker summation current transformer are connected in series, and the other end of current transformer is connected with copper busbar with appearance, and the user is powered.The ring main unit of this structure lacks the mechanical interlocks of isolating switch and vacuum circuit-breaker, can not guarantee that the latch handle of circuit breaker isolating switch when being in "on" position can not be thrown to operating position, leaves potential safety hazard.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of ring main unit is provided, and can realize the reciprocal interlocking between isolating switch and the vacuum circuit-breaker, has avoided causing having an accident because of the mistake of operating sequence.
As above design, the technical solution of the utility model is: a kind of ring main unit, comprise cabinet, be positioned at the cabinet inner and upper isolating switch, be positioned at the vacuum circuit-breaker that has linkage of isolating switch below and the isolator operation handle that has position-limit mechanism that connects with isolating switch, it is characterized in that: be provided with an interlock between isolating switch and the vacuum circuit-breaker, one end of this device is connected with isolating switch, and the other end is connected with the position-limit mechanism of isolator operation handle.
Above-mentioned interlocking mechanism main body presents " L " shape, and the trace of vertical direction passes upper and lower two fixtures that are fixed in the cabinet and is connected with the position-limit mechanism of isolator operation handle; The trace of horizontal direction is connected with the trace of vertical direction by couple axle, and end is connected with the linkage of vacuum circuit-breaker.
The utility model is simple in structure, reliable in function, easy to install and use.Can realize the irreversible effect of operating sequence by interlock restriction to operating grip in operation, avoid because the accident that the operating sequence mistake causes.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As shown in the figure: a kind of ring main unit, comprise cabinet 11, be positioned at the cabinet inner and upper isolating switch 2, be positioned at the vacuum circuit-breaker that has linkage 10 1 of isolating switch 2 belows and the isolator operation handle 3 that has position-limit mechanism 4 that connects with isolating switch.Be provided with an interlock between isolating switch 2 and the vacuum circuit-breaker 1, an end of this device is connected with isolating switch, and the other end is connected with the position-limit mechanism of isolator operation handle.Above-mentioned interlocking mechanism main body presents " L " shape, and the trace 6 of vertical direction passes upper and lower two fixtures 9 that are fixed in the cabinet and is connected with the position-limit mechanism 4 of isolator operation handle; The trace 7 of horizontal direction is connected with the trace of vertical direction by couple axle 8, and end is connected with the linkage of vacuum circuit-breaker.
