Abstract
The utility model discloses a misoperation-preventing breaker interlocking device comprising a main shaft, a main shaft pressing plate, a crank arm, a JS type mechanism state unlocking device, a linkage push rod, a breaker tripping half shaft pinch plate and a mechanism tripping half shaft. The main shaft is installed on a breaker case through a main shaft support; one end of the main shaft is provided with the main shaft pressing plate; the main shaft pressing plate is connected with the JS type mechanism state unlocking device through a connecting rod; the other end of the main shaft is connected with the crank arm; the crank arm is connected with the linkage push rod; a tripping pressing plate is mounted on the linkage push rod; and the linkage push rod is driven to move vertically by the crank arm. When the linkage push rod moves downward, the tripping pressing plat presses the breaker tripping half shaft pinch plate for achieving breaker tripping and the tail end of the bottom of the linkage push rod stops the tripping half shaft for preventing the rotation of the tripping half shaft and guaranteeing the breaker cannot be switched on. The interlocking of breaker closing and tripping and the interlocking of the JS type disconnecting and earthing switch operation mechanism are combined into one group of linkage assembly, so that the reliable action of five-prevention interlocking of the breaker and a mating cabinet of a switch cabinet is achieved.
Description
Technical field
The utility model relates to the supporting device for switching of mains supply field, relates in particular to a kind of Anti-misoperation breaker interlock.
Background technology
Require high-tension switch cabinet should possess the mistake of preventing according to national standard and divide, close circuit breaker, prevent that on-load from dividing, closing isolating switch (or stab contact), prevent disconnecting link with ground (or earth connection) power transmission, prevent " five the is anti-" functions such as charged co-grounding switch (or hanging earthing conductor).
Mostly the realization of " five is anti-" mechanical interlocking of China 12kV fixed switching cabinet is at present that employing arranges two covers respectively and is connected mechanical driving with switch cabinet grounding switch and isolator operating mechanism in the mechanism by circuit breaker, realize respectively in the time of operation JS mechanism, wherein realize breaker open operation interlock for one group, other one group is used for stoping manual operation breaker closing.Because breaker mechanism cabinet inside space is very crowded, the discrete setting of two cover interlockings need be taken to more space, part easy and mechanism self interferes, and causes misoperation.Arrange and can, because of both displacement action errors, cause circuit breaker reliably not close a floodgate or sub-switching operation discrete two cover interlockings.
Also have some producers to only have one group for realizing the interlock assembly of breaker open operation, and not operatively do not stop manual operation breaker closing interlock assembly when cutter and isolating switch, thus the interlock that does not prevent from closing circuit breaker by mistake and prevent cutter power transmission with ground.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is that prior art is improved, a kind of Anti-misoperation breaker interlock is provided, solve and in current technology, in the mechanism of circuit breaker, be provided with independently two covers and be connected mechanical driving with switch cabinet grounding switch and isolator operating mechanism, take up room many, easily interfere, cause misoperation, and the displacement action error of two interlocks can cause circuit breaker reliably not close a floodgate or separating brake.
For solving above technical problem, the technical solution of the utility model is:
A kind of Anti-misoperation breaker interlock, comprise main shaft, main shaft pressing plate, connecting lever, JS type mechanism state tripper, interlock push rod, breaker open operation semiaxis buckle, mechanism's combined floodgate semiaxis, it is characterized in that, described main shaft by spindle carrier device on circuit breaker cabinet, main shaft pressing plate is installed in main shaft one end, main shaft pressing plate is connected with JS type mechanism state tripper by connecting rod, the other end of main shaft connects connecting lever, connecting lever is connected at the interlock push rod of mechanism's right plate with device, on interlock push rod, install separating brake pressing plate, interlock push rod can be driven and be moved up and down by connecting lever, when interlock push rod moves down, separating brake pressing plate is pressed breaker open operation semiaxis buckle and is realized the power-off of breaker open operation major loop, and the interlock push rod combined floodgate semiaxis that its bottom end is blocked semicircle shape while moving down stops its rotation to guarantee that circuit breaker can not close a floodgate.Its drivening rod driving main shaft pressing plate bottom in the time pulling JS type mechanism state tripper, thereby drive main shaft rotation, the main shaft drives connecting lever bottom, thereby connecting lever promotes interlock, push rod moves down, separating brake pressing plate on interlock push rod was positioned at breaker open operation semiaxis buckle top originally, in the time that it moves down, press breaker open operation semiaxis buckle and realize the power-off of breaker open operation major loop, the bottom end of the push rod that simultaneously links is blocked combined floodgate semiaxis and is stoped its rotation to guarantee that circuit breaker can not close a floodgate.Whole device by circuit breaker divide, interlocking two covers of the isolation of combined floodgate and JS type, earthing switch operating mechanism merge into one group of linkage unit, that has realized circuit breaker and fixed switching cabinet joins cabinet " five anti-" interlocking action message, whole apparatus structure is simple, the space taking is little, can realize effectively reliably breaker open operation is linked, and stop manual operation breaker closing, avoid the appearance of accident.
Further, on described mechanism's right plate, be provided with guide pin, on interlock push rod, offering the vertical gathering sill restriction interlock push rod mating with guide pin moves in the vertical direction, utilize guide pin and gathering sill to coordinate the push rod moving direction that makes to link accurate, avoid linking push rod sideslip and do not reach fool proof effect.
Further, the top arrangement of described interlock push rod has back-moving spring, utilize the elastic force of the back-moving spring push rod that can make to link to pop up to reset and untie the lockup state of breaker open operation semiaxis buckle, mechanism's combined floodgate semiaxis, avoid occurring that mechanism's combined floodgate semiaxis is because its rotatory force is blocked interlock push rod and cannot carry out the phenomenon of closing operation.
Further, on described mechanism's right plate at the other device in the bottom of interlock push rod locating part, increase the reliability of anti-misconnection operation.
Compared with prior art, the utility model advantage is:
Anti-misoperation breaker interlock described in the utility model by circuit breaker divide, the interlocking of the isolation of combined floodgate and JS type, earthing switch operating mechanism merges into one group of linkage unit, realize breaker open operation has been linked, and stop manual operation breaker closing, prevent cutter power transmission with ground, realize the cabinet " five is anti-" of joining of circuit breaker and fixed switching cabinet and interlock; The utility model is simple in structure, and reliability is strong, simple to operate, and economic benefit is high, practical.
