Abstract
The utility model discloses an interlocking device of a high pressure isolating switch and a cabinet door, which limits the movement of a handle transmission mechanism through blocking rods of a middle door and a lower, a locking rod, and a compression spring. The utility model realizes the interlock in the pure mechanical mechanism, the structure is simple and practical, and the utility model is economic, and reliable.
Description
Technical field
The utility model belongs to the switchgear field, particularly relates to the interlock of high voltage isolator and cabinet door.
Background technology
In the high-tension switch cabinet, extinguishing arc and overvoltage protection are the new products that occurs in market in recent years.According to " five anti-" requirement, should isolating switch when closing position, Qian Zhongmen and preceding Xiamen can not be opened; Otherwise Qian Zhongmen and preceding Xiamen are not shut, and isolating switch can not close.For realizing above requirement, arc-extinction device producer adopts electrification in high voltage to show and electrical interlock mostly at present, and both middle door is adorned an electromagnetic lock, and by the control of high voltage display device locking contact, high pressure does not have electricity can open middle door; An electromagnetic lock is adorned in the Xiamen, and by the control of isolating switch auxiliary contact, isolating switch is opened and can be opened the Xiamen.This interlocking can only satisfy preceding a part of requirement, can not satisfy a part of requirement in back; And the action need power supply of electromagnetic lock was difficult for obtaining because of operating power in the Installation and Debugging stage of engineering, and operation must be adopted emergency release, makes troubles to Installation and Debugging.
Summary of the invention
To be solved in the utility model is the extinguishing arc and the awkward problem of overvoltage protection of high-tension switch cabinet, provides a kind of convenient and reliable cost low, safe interlock.
For this reason, the technical solution adopted in the utility model is such: the interlock of high voltage isolator and cabinet door, comprise operating grip, middle door lock spare and Xiamen latch fitting, it is characterized in that: it also comprises middle door shield bar, middle door lock rod, middle door bolt and Xiamen pin, following door lock rod, following door bolt, and the handle transmission mechanism, operating grip enters respectively in middle door lock spare and the Xiamen latch fitting by door lock rod in the handle transmission mechanism control and following door lock rod; Middle door bolt, following door bolt are rotationally connected with middle door shield bar and Xiamen pin respectively, respectively have stage clip on middle door shield bar and the Xiamen pin, make it have different service positions, thus the action of restriction handle transmission mechanism.
Further, described handle transmission mechanism is made up of connecting plate, trap and lock pin, and trap links to each other with following door lock rod with middle door lock rod, and drives it by connecting plate and do level or move both vertically, the motion of lock pin restriction connecting plate.Middle door bolt and following door bolt are respectively by a connecting lever and middle door shield bar and the pivot joint of Xiamen pin.
The utility model is when isolating switch during at closing position, and door lock spare during door lock rod inserts in making by the handle transmission mechanism descend door lock rod to insert the Xiamen latch fitting simultaneously, and in this moment and Xiamen all can not be opened.Isolating switch is opened hour locking lever and is subjected to the stage clip effect to deviate from latch fitting, and the cabinet door can be opened; When the cabinet door is opened, Xiamen pin and middle door shield bar are because the active position of stage clip blocks lock pin, switch knob can not be operated, door is shut and is pushed down middle door bolt in having only, the Xiamen is shut and pushed down down door bolt, door shield bar and Xiamen pin move in making, lock pin just can move, thereby the isolating switch handle can be operated.
The utility model is pure mechanical mechanism, and is simple and practical, the reliability height, and economy is also fine.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Legend is as follows: the 1-operating grip, and 2-Xiamen pin, door lock rod under the 3-, door bolt under the 4-, 5-connects connecting lever, door bolt among the 6-, door shield bar among the 7-, 8-stage clip, 9-trap, door lock rod among the 10-, 11-lock pin, 12-connecting plate
Embodiment
As shown in Figure 1, present embodiment is made up of connecting plate 12, Xiamen pin 2, middle door shield bar 7, following door lock rod 3, middle door lock rod 10, following door bolt 4, middle door bolt 6, lock pin 11 etc.Isolating switch is when closing position, and operating grip 1 is pushed down connecting plate 12, and connecting plate drives trap 9, and door lock rod 10 is moved to the left in making, and door lock spare in the insertion descends door lock rod 3 to move down simultaneously and inserts the Xiamen latch fitting, and door and Xiamen all can not be opened in this moment.Isolating switch is opened hour locking lever and is subjected to the stage clip effect to deviate from latch fitting, and the cabinet door can be opened.When the cabinet door is opened, Xiamen pin 2, middle door shield bar 7 are because the active position of stage clip 8 blocks lock pin 11, isolating switch can not be operated, door bolt 6 and following door bolt were shut and are pushed down down door bolt 4 during door was shut and pushed down in having only, by connecting lever 4 middle door shield bar 7 and Xiamen pin 2 are moved down, lock pin 11 can be moved, and isolating switch handle 1 can be operated.
Claims (3)
1. the interlock of high voltage isolator and cabinet door, comprise operating grip, middle door lock spare and Xiamen latch fitting, it is characterized in that: it also comprises middle door shield bar, middle door lock rod, middle door bolt and Xiamen pin, following door lock rod, following door bolt, and the handle transmission mechanism, operating grip enters respectively in middle door lock spare and the Xiamen latch fitting by door lock rod in the handle transmission mechanism control and following door lock rod; Middle door bolt, following door bolt are rotationally connected with middle door shield bar and Xiamen pin respectively, respectively have stage clip on middle door shield bar and the Xiamen pin, make it have different service positions, thus the action of restriction handle transmission mechanism.
2. interlock as claimed in claim 1, it is characterized in that: described handle transmission mechanism is made up of connecting plate, trap and lock pin, trap links to each other with following door lock rod with middle door lock rod, and drives it by connecting plate and do level or move both vertically, the motion of lock pin restriction connecting plate.
3. interlock as claimed in claim 1 or 2 is characterized in that: middle door bolt and following door bolt are respectively by a connecting lever and middle door shield bar and the pivot joint of Xiamen pin.
