Abstract
The utility model discloses a movable blocking mechanism of a circuit breaker chamber door of a switch cabinet. The body of the switch cabinet is fixedly provided with a first supporting seat and a second supporting seat. The circuit breaker chamber door is provided with a locking pin, a movable lock blade, a valve swinging arm and a connecting piece. The movable lock blade is provided with a first horizontal rotating shaft which is installed on the first support seat. The movable lock blade can rotate around the first horizontal rotating shaft; a latch hook is arranged at the end of the movable lock blade and the position of the latch hook is corresponding to the position of the locking pin of the circuit breaker chamber door; the valve swinging arm is provided with a second horizontal rotating shaft which is installed on the second support seat. The valve swinging arm can rotate around the second horizontal rotating shaft and is provided with a return spring; both ends of the connecting pieces are respectively articulated with the valve swinging arm and the movable locking blade. The movable blocking mechanism has simple structure, safety and reliability and can meet the requirements specified in GB3906 standard so as to ensure that the circuit breaker chamber door is locked forcibly and can not be opened when a circuit breaker is in working position, thereby protecting the personal safety of operators.
Description
Technical field
The utility model belongs to the technical field of mains switch cabinet, is specifically related to a kind of withdraw-type switch cabinet breaker chamber door blocking mechanism.
Background technology
According to GB3906 standard code requirement, the breaker chamber door of withdraw-type switch cabinet is opened and should be restricted at the switch cubicle charging operation, when breaking down, and avoids not having at closing time the circuit breaker position of deactivating, and avoids not having operating breaker divide-shut brake at closing time.But all there is weak point in present existing withdraw-type switch cabinet breaker chamber door blocking mechanism, or complex structure, or locking is unreliable, has potential safety hazard, threatens operator safety.
Summary of the invention
The purpose of this utility model is to be to overcome above-mentioned shortcoming and a kind of withdraw-type switch cabinet breaker chamber door blocking mechanism is provided, and it is simple in structure, and safe and reliable.
For achieving the above object, withdraw-type switch cabinet breaker chamber door blocking mechanism of the present utility model comprises switch cabinet body and breaker chamber door, switch cabinet body is fixed with first bearing and second bearing, the breaker chamber door is provided with lock pin, its main feature is that it also is provided with movable locking plate, valve swing arm, brace, and movable locking plate is provided with first horizontal rotating shaft, first horizontal rotating shaft is installed on first bearing, and movable locking plate can rotate around first horizontal rotating shaft; Movable locking plate end is provided with latch hook, and the position of latch hook is corresponding with the position of breaker chamber door lock pin; The valve swing arm is provided with second horizontal rotating shaft, and second horizontal rotating shaft is installed on second bearing, and the valve swing arm can be rotated around second horizontal rotating shaft; The valve swing arm is provided with back-moving spring; The two ends of brace are hinged with valve swing arm and movable locking plate respectively.
Be preferably, the back-moving spring of described valve swing arm is a torsion spring.
The utlity model has following advantage and effect:
1, the utility model can reach the requirement of GB3906 standard code; when making circuit breaker be in the service position; breaker chamber door positive lock and can not opening; avoid not having at closing time the circuit breaker position of deactivating; and avoid not having operating breaker divide-shut brake at closing time; the security of operation that helps switch cubicle is protected operating personnel's personal safety better.
2, after the utility model made circuit breaker fall back on test position from the service position, the breaker chamber door can be opened.
3, the utility model is simple and practical, and operation is reliable.
Description of drawings
Fig. 1 is the perspective view of a kind of specific embodiment of the utility model.
Fig. 2 is a user mode schematic diagram embodiment illustrated in fig. 1.
Embodiment
Fig. 1, withdraw-type switch cabinet breaker chamber door blocking mechanism shown in Figure 2 comprise switch cabinet body and breaker chamber door 2, switch cabinet body is installed with first bearing 3 and second bearing 4, breaker chamber door 2 is provided with lock pin 21, it also is provided with movable locking plate 5, valve swing arm 6, brace 7, movable locking plate 5 is provided with first horizontal rotating shaft 51, first horizontal rotating shaft 51 is installed on first bearing 3, and movable locking plate 5 can rotate up and down around first horizontal rotating shaft 51; Movable locking plate 5 ends are provided with latch hook 52, and the position of latch hook 52 is corresponding with the position of breaker chamber door lock pin 21; Valve swing arm 6 is provided with second horizontal rotating shaft, 61, the second horizontal rotating shafts 61 and is installed on second bearing 4, and valve swing arm 6 can be rotated around second horizontal rotating shaft 61; Valve swing arm 6 is provided with the torsion spring (not shown), and torsion spring applies torsion to valve swing arm 6; The two ends of brace 7 are hinged with valve swing arm 6 and movable locking plate 5 respectively.
The foregoing description occupation mode is as follows:
Shutdown device chamber behind the door, when circuit breaker enters the service position from test position, circuit breaker promotes valve swing arm 6 and rotates around second horizontal rotating shaft 61, driving brace 7 is moved, brace 7 further drive activity locking plates 5 rotate around first horizontal rotating shaft 51, make the latch hook 52 of movable locking plate fasten the lock pin 21 of breaker chamber, thus positive lock breaker chamber door 2.So breaker chamber door 2 can not be opened when circuit breaker was in the service position.
On the contrary, when circuit breaker falls back on test position from the service position, valve swing arm 6 breaks away from circuit breaker, so under the torsion spring effect, backward rotation takes place around second horizontal rotating shaft 61 in valve swing arm 6, drives brace 7 answers and moves to original position, and brace 7 further drive activity locking plates 5 turn to original position around first horizontal rotating shaft 51, make the latch hook 52 of movable locking plate break away from breaker chamber door lock pin 21, the breaker chamber door just can be opened.
