Description
Technical field
The present invention relates to a kind of armored withdraw type metal enclosed switch cabinet of 40.5kV middle.
Background technology
40.5kV the design that is console mode that the armored withdraw type ac metal closing switch gear uses in the market.Adopt the console mode design, the circuit breaker cart size is big, highly high, the center of gravity height, can not about, about the location, can not before and after interlocking, can't carry out up and down that six orientation are spacing to circuit breaker cart all around, therefore following disadvantage is often arranged in use: one cooperates bad with switch cubicle, the big electrokinetic moment of the arm of force is big when the service position, can make moving contact be in the contact labile state, produce uncertain oscillatory forces, the circuit breaker cart layback, easily be pressed onto the people after the release, manipulate dangerous; Its two, the temperature rise of dynamic/static contact poor fit, contact is easily burnt, and then cause whole switch cubicle current supply circuit in paralyzed state, can not work.
Summary of the invention
The armored withdraw type metal enclosed switch cabinet that the purpose of this invention is to provide the 40.5kV middle, it has overcome the layback of the existing circuit breaker cart of background technology switch cubicle, easily be pressed onto the people after releasing, operation is dangerous, dynamic/static contact poor fit, contact are easily burnt, current supply circuit is in paralyzed state, inoperable deficiency.
The technical solution adopted for the present invention to solve the technical problems is:
40.5kV the armored withdraw type metal enclosed switch cabinet of middle, it comprises a cabinet main body, a circuit breaker cart and a lock connector.Be provided with fixed contact in this cabinet main body.This circuit breaker cart is provided with moving contact and chassis car, this chassis car is provided with quiet vehicle frame and screw mandrel propulsive mechanism, this circuit breaker cart enters after the cabinet main body and constitutes the front and back relation of being slidingly connected between the cabinet main body, and this screw mandrel propulsive mechanism can promote circuit breaker cart so that it slides in front and back between service position and test position.This lock connector is located between cabinet main body and the chassis car and can selects interlocking or pine oil, and this lock connector was in the interlocking state after this circuit breaker cart entered the cabinet main body.
In the preferred embodiment of the present invention, this lock connector is located between the quiet vehicle frame of cabinet main body and chassis car and can selects interlocking or pine oil.
In the preferred embodiment of the present invention, this lock connector comprises an interlocking plate, an elastomer and an elastomer.This interlocking plate slides and is located on the circuit breaker cart.This elastomer connects the interlocking plate, and this elastomer makes the interlocking plate be subjected to outside elastic force.This interlocking hole is located on the cabinet main body, and this interlocking plate stretched out circuit breaker cart and this interlocking hole of pegging graft after this circuit breaker cart entered the cabinet main body under the elastic force effect.
In the preferred embodiment of the present invention, the end of this interlocking plate is arranged for ease of the chamfering of turnover.
In the preferred embodiment of the present invention, be installed with handle after this interlocking plate.
In the preferred embodiment of the present invention: be provided with guide rail in this cabinet main body, be provided with opening horizontal concrete chute the preceding in this guide rail; This handcart is provided with wheel; This wheel rolling is connected in the horizontal concrete chute of guide rail.
In the preferred embodiment of the present invention, this horizontal concrete chute runs through; This wheel is an I shape, and it comprises that a wheel, two that is fit to horizontal concrete chute is fixedly arranged on the spacer of wheel left and right side respectively, and this wheel rollably is located in the horizontal concrete chute, and this two spacer is abutted against the guide rail left and right side respectively.
In the preferred embodiment of the present invention, this horizontal concrete chute back is a center of circle arc the preceding, and this arc adapts to wheel.
The technical program is compared with background technology: after circuit breaker cart enters the cabinet main body, (1). this lock connector can limit quiet vehicle frame and the forward and backward slip of screw mandrel propulsive mechanism on the car of chassis, rock, and this quiet vehicle frame and screw mandrel propulsive mechanism can be controlled the forward and backward slip of circuit breaker cart and stop; (2), the horizontal concrete chute of this guide rail can slide, rock in limiting circuit breaker handcart upper and lower, left and right, therefore all around six orientation are spacing up and down for circuit breaker cart, moving contact is in the contact stabilization state during engagement of quiet, moving contact, guarantee fixed contact and moving contact positive engagement, the dynamic/static contact that is caused by electric power when effectively avoiding moving meshes not good and adverse consequences that cause.After this circuit breaker cart enters the cabinet main body,, manipulate safety no matter be in the service position or test position can both prevent circuit breaker cart layback.Because the terminal head of this interlocking plate is arranged to chamfering, interlocking is firm, and pine oil is convenient.When circuit breaker cart entered the cabinet main body, the terminal head of interlocking plate with regard to the interlocking hole of just pegging graft automatically, can be realized automatic interlocking under the elastic force effect.
