Abstract
The invention provides an interlocking device of a high-tension switch gear. The interlocking device comprises a lorry frame, an electromagnetic mechanism and a mechanical locking device, wherein the electromagnetic mechanism and the mechanical locking device are arranged on the lorry frame; the electromagnetic mechanism dead point round pin of the electromagnetic mechanism is connected with a cable accelerator through a lever mechanism; and the cable accelerator is connected with the mechanical locking device through a rotating mechanism. Compared with the prior art, the interlocking device provided by the invention has the advantages that the structure is simple, and the manufacturing is convenient; by rotating a handle to a segmentationally locked position, a crank arm on a handle shaft simultaneously rotates clockwise; the cable accelerator drives a lower adaptor to move down, a spring is compressed, a pressing sheet moves downwards, the larger end of a lever moves downwards, the smaller end of the lever moves up and pushes a mechanism dead point shaft to pass through a dead point, thus brake separating operation is completed under the action of a brake separating spring of a circuit breaker, thereby forcibly disconnecting the circuit breaker and realizing a function of preventing on-load disconnecting link; since the lever props the mechanism dead point all the time, the mechanism can not store energy and further can not switch in the circuit breaker, thereby realizing the function of preventing mistakenly switch in the circuit breaker; and the interlocking device is safe and reliable.
Description
Technical field
The present invention relates to a kind of high voltage switchgear interlock.
Background technology
At present China produces and the high voltage switchgear that uses has two kinds of handcart cabinet and stationary cabinets; And stationary cabinet is simple in structure with it; Technological requirement is low, and low price is easy to operate and be used widely; Especially it does not need the bigger space of manipulating, and is one of main high voltage cabinet type of composite type cabinet type transformer substation employing.No matter fixed switchgear is distribution magnetic operating mechanism or spring operating mechanism, employing all be box switch cubicle mechanical locking device.What this device adopted is mandatory mechanical latching mode, has characteristics such as easy and simple to handle, safe, reliable, satisfies complete set of equipments " five is anti-" functional requirement fully; Device is through bent sub, connecting rod; Draw bar links to each other with isolating switch, earthed switch, adjusts also very convenient, but just very complicated with being connected of vacuum circuit-breaker operating mechanism; Also be difficult for adjustment, have two problems; 1: maintenance for ease, vacuum circuit-breaker and operating mechanism device are on the simple and easy handcart that can advance.During installation, the circuit breaker cart propelling is put in place, be fixed by bolts on the cabinet of switch cubicle, connect main bus bar again.During the circuit breaker maintenance, at first main bus bar and handcart set bolt are unclamped, could handcart be shifted out.Because locking device is hard connection with being connected of breaker mechanism; Jockey must be through the aperture above the handcart side plate; Could be connected with the separating brake pallet on the operating mechanism; Therefore, require handcart location and spring mechanism or electromagnetic mechanism location to want accurately, this has increased cabinet and handcart manufacture difficulty undoubtedly.2: mechanical locking device is installed on the cabinet, therefore operating mechanism is installed on the vehicle frame; Will be from the mechanical locking device turning handle to breaker operation mechanism through many places switching and location, it is many to connect number of packages, and the difficult processing of part; Install loaded down with trivial detailsly, be difficult for adjustment, poor reliability.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of high voltage switchgear interlock and prevent to close circuit breaker, safe and reliable purpose to reach by mistake.
In order to solve the problems of the technologies described above technical scheme of the present invention be; A kind of high voltage switchgear interlock; Comprise the handcart frame; Be arranged on electromagnetic mechanism and mechanical locking device on the handcart frame, the electromagnetic mechanism dead point round pin post of described electromagnetic mechanism is connected with acceleration cable through leverage, and acceleration cable is connected with mechanical locking device through rotating mechanism.
Described rotating mechanism comprises handle, connecting lever, top connection; Described handle is connected with mechanical locking device, and described handle is provided with connecting lever, and described connecting lever is connected with top connection through acceleration cable.
Described leverage comprises lever, pressing plate, spring, lower contact; One end of described lever is connected with electromagnetic mechanism through electromagnetic mechanism dead point round pin post, and the other end is connected with pressing plate, and pressing plate is connected with lower contact through spring, and described acceleration cable passes top connection successively, and lever is connected with lower contact behind pressing plate, the spring.
Described lever is provided with the balance pivot straight pin, and lever is provided with the hole, and described balance pivot straight pin passes the hole and is fixed on the cabinet.
Described top connection is fixed on the handcart sidewall.
Described lower contact is fixed on the handcart frame through fixed support.
Described acceleration cable is connected with connecting lever through square neck bolt.
The present invention compared with prior art, and is simple in structure, easily manufactured, through the position of turning handle to the segmentation locking; Connecting lever on the Handle axis also clockwise rotates simultaneously, and drive lower contact through acceleration cable and move downward, length of spring compressed, compressing tablet moves downward; The big end of lever moves down, and small end moves up, and small end is being chosen mechanism's dead point axle through the dead point, under the effect of breaker open operation spring; The action of completion separating brake, thus the forced cut-out device breaks off, and realizes preventing on-load broaching tool lock function, because this moment, lever was chosen the mechanism dead point always; Mechanism can not energy storage, also just can not carry out the combined floodgate of circuit breaker, has realized the function that prevents that mistake from closing circuit breaker, and is safe and reliable.
