Abstract
A load switch operating mechanism comprises a panel, a main shaft, a cabinet door locking lever and a load switch operation shaft. The cabinet door locking lever is in linkage with the main shaft; the panel is provided with a main shaft operation aperture and a load switch operation aperture; the main shaft is sleeved with an eccentric sheave; a linkage guide rod is arranged between the eccentric sheave and the load switch operation aperture; the lower end of the linkage guide rod is connected with a baffle plate; and a return spring is arranged on the linkage guide rod. According to the utility model, an eccentric sheave is sleeved on the main shaft to drive the linkage guide rod, so as to realize bidirectional interlock of the isolation switch and the load switch; and the load switch operating mechanism has simple reasonable structure, good anti-error performance and guaranteed product safety performance.
Description
Technical field
This practicality relates to power transmission and distribution switchgear technical field, is specifically related to a kind of on-load switch operating mechanism.
Background technology
In the design of the operating mechanism of existing on-load switch, generally include panel, main shaft, cabinet couplet on the door locking bar and on-load switch operating axis, cabinet couplet on the door locking bar and main shaft interlock.Operation by the main shaft handle hole on the panel and on-load switch handle hole realize on-load switch deciliter and isolating switch, earthed switch deciliter, interlocking between isolating switch, earthed switch and on-load switch is realized by two disks in on-load switch and the isolating switch rotating shaft, but this interlocking can only realize that on-load switch is to the unidirectional interlocking of isolating switch and earthed switch, and can not realize isolating switch to the interlocking of on-load switch, misoperation easily appear in that on-load switch is in service thus.
The utility model content
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art, a kind of technical scheme to be provided, can realize the two-way interlocking of isolating switch and on-load switch, and its simple and reasonable, anti-error performance is good, handling safety is reliable.
A kind of on-load switch operating mechanism of the utility model, comprise panel, main shaft, cabinet couplet on the door locking bar and on-load switch operating axis, cabinet couplet on the door locking bar and main shaft interlock, panel is provided with main shaft handle hole and on-load switch handle hole, it is characterized in that being arranged with on the main shaft eccentric wheel, be provided with chain guide rod between eccentric wheel and on-load switch handle hole, chain lower end of the guide rod is connected with baffle plate, and chain guide rod is provided with returning spring.By the elastic force of returning spring, make chain guide rod upper surface all the time with the main shaft of isolating the ground connection cutter on the eccentric wheel surface contact; When eccentric wheel minimum point down the time, the baffle plate of the lower end of chain guide rod can not exceed the handle hole of on-load switch.When cabinet door opening, blocking lever locking main shaft, main shaft can not rotate, and isolating switch can not close a floodgate.When the cabinet door closure state, rotatable main shaft, isolating switch closes a floodgate, and in the time of rotating spindle, eccentric wheel also rotates, and eccentric wheel turns down chain guide rod, and baffle plate moves down, and baffle plate is blocked the on-load switch handle hole, guarantees that on-load switch can not close a floodgate; Work as rotating spindle, isolating switch is opened, and eccentric wheel also rotates, and eccentric top breaks away from chain guide rod, under the effect of returning spring, move on the chain guide rod, move on the baffle plate, baffle plate is not positioned on the on-load switch handle hole, and on-load switch can close a floodgate, and realizes that isolating switch and on-load switch are chain.
During concrete enforcement, be provided with upper support bar and lower support bar, the end of upper support bar and lower support bar is provided with supported hole, and chain leader casing is in the supported hole of upper support bar and lower support bar.It is to support and fixing chain guide rod that upper support bar and lower support bar mainly act on.
During concrete enforcement, the middle part of chain guide rod is provided with to the changeover portion of panel direction folding, upper support bar be positioned at changeover portion above, the upper and lower side of returning spring is located at respectively on upper support bar and the changeover portion.
The beneficial effects of the utility model are: the utility model drives chain guide rod by being arranged with eccentric wheel at main shaft, realizes isolating switch and the two-way interlocking of on-load switch, and its simple and reasonable, anti-error performance is good, guaranteed the security of products energy.
