Abstract

The utility model relates to the technical field of high-voltage switch cabinets and especially relates to an interlocking mechanism of a vacuum ring main unit. The interlocking mechanism used for an isolation switch, a circuit breaker and a grounding switch of the vacuum ring main unit mainly includes a wire outlet cabinet provided with a trip half shaft and a rotary main shaft connected with a swing arm via a connecting rod. A bearing is arranged between the swing arm and the connecting rod. The trip device is installed on the trip half shaft. The trip half shaft is connected with a cam through a pull rod. The interlocking mechanism has beneficial effects that the interlocking mechanism is simple in structure, easy to operate, high in safety performance, flexible and convenient in operation and not easy to get stuck; operation is smooth in a process of getting the isolation switch, the circuit breaker and the grounding switch interlocked and a problem that a traditional linkage method may cause clamping easily is solved.

Description

Vacuum ring main unit isolating switch and circuit breaker and earthed switch interlocking device
Technical field
The utility model relates to high-tension switch cabinet technical field, relates in particular to a kind of interlocking device of vacuum ring main unit.
Background technology
National requirements 10kV high-voltage board need to meet five anti-requirements, and five anti-requirements comprise 1, prevent that on-load from dividing, closing isolating switch; 2, prevent from dividing by mistake, closing by mistake circuit breaker, on-load switch, contactor; 3, prevent from closing when earthed switch is in the close position circuit breaker, on-load switch; 4, prevent from closing earthed switch in charged mistiming; 5, prevent mistakenly entering into charged chamber.Traditional isolating switch and circuit breaker and earthed switch interlocking device adopt the kind of drive of interlock often to occur card, even cause the malfunctioning equipment that causes of operation impaired, even occur security incident.
The applicant sees above-mentioned deficiency, adheres to research and innovation, excelsior spirit, utilizes the method for professional science, proposes a practical solution, therefore proposes this case application.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, and a kind of reliable working performance is provided, and operates smooth and easy vacuum ring main unit isolating switch and circuit breaker and the earthed switch interlocking device of timing that do not block.
For achieving the above object, the utility model adopts following technical scheme:
Vacuum ring main unit isolating switch and circuit breaker and earthed switch interlocking device, mainly comprise outgoing line cabinet 1; Described outgoing line cabinet 1 is respectively arranged with dropout semiaxis 2 and rotating spindle 3, and rotating spindle 3 connects swing arm 9 by connecting rod 4, between swing arm 9 and connecting rod 4, bearing 91 is set, and trip gear 6 is arranged on dropout semiaxis 2.
Described dropout semiaxis 2 connects cam 7 by pull bar 5.
In described swing arm 9, baffle plate 10 is installed, baffle plate 10 is positioned at the front end of isolating switch and earthed switch.
Described rotating spindle 3 connects respectively connecting rod 4 and earthed switch axle 12 by swinging block 11.
Its profitable fruit is the utility model: simple in structure easy to operate, security performance is high, and flexible and convenient operation is difficult for stuck, and in the time of by isolating switch and circuit breaker and earthed switch interlocking, its operating process is smooth and easy, overcomes traditional interlock mode problem that easily card pauses.
accompanying drawing explanation:
The structural representation that accompanying drawing 1 is the utility model;
The end view that accompanying drawing 2 is the utility model.
embodiment:
In order to make juror can the object of the utility model, feature and function be had further and be understood, hereby lift preferred embodiment and coordinate graphic being described in detail as follows:
Referring to Fig. 1 ~ 2 and show, is the structural representation of the preferred embodiment of the utility model,
Vacuum ring main unit isolating switch and circuit breaker and earthed switch interlocking device, mainly comprise outgoing line cabinet 1; Described outgoing line cabinet 1 is respectively arranged with dropout semiaxis 2 and rotating spindle 3, and rotating spindle 3 connects swing arm 9 by connecting rod 4, between swing arm 9 and connecting rod 4, bearing 91 is set, and trip gear 6 is arranged on dropout semiaxis 2.Described dropout semiaxis 2 connects cam 7 by pull bar 5.In the swing arm 9 of stating, baffle plate 10 is installed, baffle plate 10 is positioned at the front end of isolating switch and earthed switch.
During operation, during breaker closing, rotating spindle 3 rotates by connecting rod 4 and swing arm 9 and drives baffle plate 10 up to swing and block isolating switch and earthed switch, and now isolating switch and earthed switch cannot operate, and avoid load operation isolating switch.And the kind of drive that swings up and down of swing arm 9 overcome existing interlock mode and easily occurred card, and the serious problem of the operation sound.When isolating switch closes a floodgate, isolating switch vertical shaft 7 drives front cam 7 to rotate now trip gear 6 separation, and earthed switch axle 12 cannot be operated by locked earthed switch.When earthed switch closes a floodgate, dropout semiaxis 2 is locked by circuit breaker, and circuit breaker cannot operate; Isolating switch is blocked by baffle plate 10, and isolating switch cannot operate, equipment live while placing earthed switch combined floodgate.
Described rotating spindle 3 connects respectively connecting rod 4 and earthed switch axle 12 by swinging block 11.The effect of control connection connecting rod 4 and earthed switch axle 12 is flexibly played simultaneously in the setting of swinging block 11.
Certainly, above diagram is only the utility model better embodiment, not with this, limits the scope of application of the present utility model, therefore, everyly in the utility model principle, make equivalent change and all should be included in protection range of the present utility model.
