Abstract
The utility model discloses a switch cabinet misoperation-preventive locking device using protection devices, comprising a master cabinet, a first slave cabinet, a second slave cabinet and a switch. The master cabinet includes an electromagnetic lock and a master cabinet protection device; the first slave cabinet includes a master cabinet locking judgment device 1 and a first slave cabinet protection device; the second slave cabinet includes a master cabinet locking judgment device 2 and a second slave cabinet protection device; and the switch acquiring signals of the first slave cabinet protection device and the second slave cabinet protection device is connected with the electromagnetic lock installed on the master cabinet through the master cabinet protection device. According to the switch cabinet misoperation-preventive locking device using protection devices, existing communication equipment is used to replace original hard-wired connection so that the whole device has less connection wires and is flexible in configuration. When locking conditions of the master cabinet needs to be increased, operations can be carried out on a computer without the need to change a circuit.
Description
Technical field
The utility model relates to distribution and uses the switch cabinet field, is specifically related to a kind of switch cubicle anti-misoperation locking device of more convenient reliable application protective device.
Background technology
Between now widely used switch cabinet, anti-misoperation locking is all realized by latching electromagnet, from barring condition (dry contact) string of cabinet, at electromagnetic lock, starts loop, to reach this cabinet locking purpose.Hardwire more complicated between cabinet, some outside barring condition is distant, and placing oversize cable has increased disturbing factor, and cost is high; During the barring condition change, need be redesigned whole locking determination circuit, the repacking cycle is long.
The utility model content
Goal of the invention: for solving the deficiencies in the prior art, the utility model provides a kind of switch cubicle anti-misoperation locking device of more convenient reliable application protective device.
Technical scheme: for achieving the above object, the switch cubicle anti-misoperation locking device of application protective device of the present utility model, comprise that this cabinet, first is from cabinet, second from cabinet and switch; Described cabinet comprises electromagnetic lock and this cabinet protective device; Described first comprises that from cabinet this cabinet locking decision maker one and first is from the cabinet protective device; Described second comprises that from cabinet this cabinet locking decision maker two and second is from the cabinet protective device; Gather first from cabinet protective device and the second switch from cabinet protective device signal by this cabinet protective device be arranged on this electromagnetic lock cashier's office in a shop and be connected.
As preferably, described cabinet locking decision maker one is connected with electromagnetic lock from cabinet protective device, switch and this cabinet protective device by first; Described cabinet locking decision maker two is connected with electromagnetic lock from cabinet protective device, switch and this cabinet protective device by second.
Beneficial effect: the switch cubicle anti-misoperation locking device of application protective device of the present utility model; increase a logic blocking output contact on the protective device of each connection barring condition; gather the signal of each logic blocking output contact by switch; utilize the respectively communication between device to realize the transmission of barring condition; then carry out the logic judgement in this cabinet protective device inside; while meeting barring condition, start the electromagnetic lock of this cabinet.The switch cubicle anti-misoperation locking device of application protective device of the present utility model utilizes existing communication apparatus to replace original hardwire to connect, and the wiring of whole device is reduced, flexible configuration; Operate and get final product on computers when needs increase the barring condition of this cabinet, without circuit is changed.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the switch cubicle anti-misoperation locking device of application protective device of the present utility model, comprise that this cabinet 1, first is from cabinet 2, second from cabinet 3 and switch 4; Described cabinet 1 comprises electromagnetic lock 11 and this cabinet protective device 12; Described first comprises that from cabinet 2 this cabinet locking decision maker 1 and first is from cabinet protective device 22; Described second comprises that from cabinet 3 this cabinet locking decision maker 2 31 and second is from cabinet protective device 32; Gathering first is connected with the electromagnetic lock 11 being arranged on this cabinet 1 by this cabinet protective device 12 with the second switch 4 from cabinet protective device 32 signals from cabinet protective device 22.
In the present embodiment, described cabinet locking decision maker 1 is connected with electromagnetic lock 11 from cabinet protective device 22, switch 4 and this cabinet protective device 12 by first; Described cabinet locking decision maker 2 31 is connected with electromagnetic lock 11 from cabinet protective device 32, switch 4 and this cabinet protective device 12 by second.
The switch cubicle anti-misoperation locking device of application protective device of the present utility model; increase a logic blocking output contact on the protective device of each connection barring condition; gather the signal of each logic blocking output contact by switch 4; utilize the respectively communication between device to realize the transmission of barring condition; then carry out the logic judgement in this cabinet protective device 12 inside; while meeting barring condition, start the electromagnetic lock 11 of this cabinet 1.The switch cubicle anti-misoperation locking device of application protective device of the present utility model utilizes existing communication apparatus to replace original hardwire to connect, and the wiring of whole device is reduced, flexible configuration; Operate and get final product on computers when needs increase the barring condition of this cabinet 1, without circuit is changed.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
