Abstract
The invention relates to a safety isolating device of an isolating valve of a drawout breaker, which comprises a mounting bus and a chassis of a connecting piece, wherein the opening position of the front part of the chassis is provided with baffles capable of transversely moving; two baffles are arranged and respectively relatively move; and each baffle is provided with a longitudinal jack which corresponds to the connecting piece; when the baffle moves to a certain position, the positions of the jack and the connecting piece deviate, thereby achieving the goal of isolating. The baffles are reset by tension springs after moving; and both ends of the baffles are provided with pull rods, and the baffles are driven to move by the pull rods. After the design is adopted by the safety isolating device, the connecting piece in the chassis can be effectively isolated from the outside after the breaker is moved out of a drawing frame, thereby ensuring the safety of the drawout breaker in the use process.
Description
Technical field
The present invention relates to taking out of a kind of drawout breaker and be used to prevent the isolating door safety guard that shocks by electricity in the frame.
Background technology
Existing a kind of device is to drive slide plate that circuit breaker moves move back and forth the actuating safety screen and open or close in taking out frame by taking out on the frame.Safety screen is opened the circuit breaker bus is entered, by connector with take out the frame bus and be electrically connected.Circuit breaker is after take out frame and shift out, and safety screen is closed to make and taken out bus charged on the frame and connector and external isolation.This device defect be when circuit breaker shift out take out frame after, operation is taken out frame slide plate travel mechanism and slide plate is moved back and forth also can open or close by the actuating safety screen, or directly acts on safety screen and also can open safety screen.So just can not satisfy circuit breaker shifts out and takes out the requirement that can not open safety screen behind the frame.
Then adopt by circuit breaker and promote the device that a guide rod actuating safety screen is opened, circuit breaker shifts out to be taken out behind the frame operation and takes out frame slide plate travel mechanism and slide plate is not moved back and forth can open by the actuating safety screen.This device shifts out and takes out the requirement that can not open safety screen behind the frame in order to satisfy circuit breaker, has added the device that the full baffle plate in a lock set Dingan County is opened.Shift out at circuit breaker like this and must carry out the operation of locked secure baffle plate at once after taking out frame, otherwise if touch the guide rod that the actuating safety screen is opened, safety screen just can be opened, or circuit breaker put into take out the lock operation that will remove safety screen before the frame, otherwise moving circuit breaker in taking out frame, operation running circuit breaker operating mechanism will damage associated components.
Summary of the invention
Based on the problems referred to above, a kind of isolating door safety insulating device of drawout breaker and the isolating door safety guard of linkage self-locking device, interlock command device composition are provided, the present invention is an isolating door safety insulating device wherein.
For achieving the above object, the present invention is achieved through the following technical solutions:
Device of drawout breaker isolating door safe isolating, comprise the underframe that bus and connector are installed, transversely movable baffle plate is installed at open front place at underframe, described baffle plate is set to two baffle plates and relatively moves respectively, have on each baffle plate that jack is corresponding with connector longitudinally, when baffle plate moved to certain position, the position deviation of jack and connector reached the purpose of isolation.
Two baffle plate subtends move, and when jack moved to the connector position, the jack on two baffle plates was overlapped, can reach the purpose of unlatching like this, thereby allow terminal to insert connector.
The extension spring that described baffle plate and has reset function is connected, and baffle plate moves the back and resets by extension spring, spurs extension spring in the baffle plate moving process, and extension spring produces the pulling force of replying to baffle plate; One end of described extension spring is fixed on the aperture of baffle plate, and the other end is fixed on the frame of underframe.
For guaranteeing the full implementation of previous step, both sides and middle several slot rollings parallel that be provided with at baffle plate with the baffle plate moving direction, one roller is installed in the slot rolling, roller is installed on the underframe by pin, roller can rotate and roll in slot rolling around pin, can guarantee the linearity of baffle plate stroke like this and reduce resistance in the moving process.
In the moving process of baffle plate, need so pull bar is installed, drive moving of baffle plate by certain external force by pull bar at the two ends of baffle plate.When draw rod positions locked, baffle plate can not be moved.
Through after the above-mentioned design, after take out frame and shift out, connector and the outside of underframe inside effectively can be isolated the fail safe in use of assurance drawout breaker at circuit breaker.

Embodiment
As shown in Figure 1, and in conjunction with Fig. 2 Fig. 3.
Device of drawout breaker isolating door safe isolating of the present invention, comprise the underframe 1 that bus and connector 2 are installed, at the open front place of underframe 1 transversely movable baffle plate 3 is installed, described baffle plate 3 is set to two baffle plates 3 and relatively moves respectively, have on each baffle plate 3 that jack 4 is corresponding with connector 2 longitudinally, when baffle plate 3 moved to certain position, the position deviation of jack 4 and connector 2 reached the purpose of isolation.
Two baffle plate 3 subtends move, and when jack 4 moved to connector 2 positions, the jack 4 on two baffle plates 3 was overlapped, can reach the purpose of unlatching like this, thereby allow terminal to insert connector 2.
The extension spring 7 that described baffle plate 3 and has reset function is connected, and described baffle plate 3 moves the back and resets by extension spring 7, pulling extension spring 7 in baffle plate 3 moving process, and 7 pairs of baffle plates of extension spring 3 produce the pulling force of replying; One end of described extension spring 7 is fixed on the aperture of baffle plate 3, and the other end is fixed on the frame of underframe 1.
For guaranteeing the full implementation of previous step, both sides and middle several slot rollings 9 parallel that be provided with at baffle plate 3 with baffle plate 3 moving directions, one roller 8 is installed in the slot rolling 9, roller 8 is installed on the underframe 1 by pin 5, roller 8 can rotate and in 9 li rollings of slot rolling around pin 5, can guarantee the linearity of baffle plate 3 strokes like this and reduce resistance in the moving process.
In the moving process of baffle plate, need so pull bar 6 is installed, drive moving of baffle plate 3 by certain external force by pull bar 6 at the two ends of baffle plate 3.In the time of pull bar 6 locking positions, baffle plate 3 can not be moved.
Through after the above-mentioned design, after take out frame and shift out, connector and the outside of underframe inside effectively can be isolated the fail safe in use of assurance drawout breaker at circuit breaker.
