Detailed Description

The following will combine the drawings of the embodiments of the present invention to further describe the technical solution of the present invention, and the present invention is not limited to the following specific embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

As shown in fig. 1, a switch power supply anti-collision interconnection lock includes: three conversion cabinet and two contact cabinets, the inside of each conversion cabinet has first cubical switchboard and second cubical switchboard, be provided with main power switch and control circuit in the first cubical switchboard, be provided with stand-by power supply control system in the second cubical switchboard, and be provided with door plant and lower door plant on each conversion cabinet, it closes first cubical switchboard to go up door plant movable cover, lower door plant movable cover closes the second cubical switchboard, be provided with first lock on the door plant, be provided with the second tool to lock on the lower door plant, first tool to lock and the second tool to lock on each conversion cabinet only can open one in the same time, each contact cabinet is used for connecting two adjacent conversion cabinets, and each contact is provided with the third door body on the cabinet, be provided with the third tool to lock on the third door body, the third tool to lock is used for opening the third door body.

Specifically, the main power supply switch, the control circuit of the main power supply switch and the standby power supply control system in each conversion cabinet are used for providing electricity for an area, that is, when the power supply of the area fails, that is, when the standby power supply needs to be used, the main power supply switch and the control circuit of the main power supply switch are automatically disconnected due to the failure of the power supply, at the moment, the second lock needs to be opened, then the lower door plate needs to be opened, and then the standby power supply control system is opened, so that the area is supplied with electricity through the standby power supply. That is, three conversion cabinets are used to control the power supply to three areas. It is worth mentioning that when the power supply source and the standby power source in one area simultaneously fail, that is, the main power supply switch, the control circuit thereof and the standby power control system of the corresponding conversion cabinet are simultaneously turned off. In order to guarantee the power supply problem of the area, the contact cabinet connected with the conversion cabinet needs to be opened, then the contact cabinet is connected with another conversion cabinet, and the power supply of the power supply source or the standby power supply connected with the other conversion cabinet is supplied to the area, so that the area can be well guaranteed to continue to supply power stably.

In order to avoid large-scale failure or safety problems caused by power utilization conflict in a corresponding area due to the fact that a power supply source and a standby power supply of one conversion cabinet are opened simultaneously, an upper door plate and a lower door plate are arranged on each conversion cabinet, a first lock is arranged on the upper door plate, a second lock is arranged on the lower door plate, it is worth mentioning that the first lock and the second lock on each conversion cabinet can be opened only one at the same time, specifically, five different first lock bodies are arranged on each first lock body, the five first lock bodies are connected in sequence, five different second lock bodies are arranged on each second lock body, and the five second lock bodies are connected in sequence. That is, only five first locks are opened to unlock the first lock and only five second locks are opened to unlock the second lock.

Furthermore, switching power supply anticollision liaison lock still includes a plurality of keys, and is different between a plurality of keys, and five first locks are opened through five keys in proper order, and five second locks are opened through five keys in proper order, and eight third locks are opened through eight keys in proper order.

Five different keys are needed to open the five first lock bodies because the five first lock bodies are different, and five different keys are needed to open the five second lock bodies because the five second lock bodies are different. That is, if five first locks do not have five corresponding keys to unlock, the first lock cannot be unlocked, that is, the main power switch and the control circuit thereof cannot be operated, and if five second locks do not have five corresponding keys to unlock, the second lock cannot be unlocked, that is, the standby power control system cannot be operated.

In the above embodiment, each third lock is provided with eight different third lock bodies, and the eight third lock bodies are connected in sequence. That is to say, only eight third locks are opened and can be opened the third tool to lock, because eight third locks are inequality, consequently need use eight different keys to open it, that is to say, the third tool to lock does not have eight corresponding keys to unlock eight third locks, will fail to open the third tool to lock.

It is worth mentioning that the number of keys is less than the total number of the first lock bodies on three first locks, the second lock bodies on three second locks and the third lock bodies on two third locks. That is, there is a lock body using the same key among the first lock, the second lock and the third lock, and there is only one corresponding key. For example, the keys corresponding to the first locks of the three conversion cabinets are represented by letters, that is, the key for opening the first lock of the first conversion cabinet 100 is A, B, C, D, E, the key for opening the first lock of the second conversion cabinet 300 is A, F, G, H, I, the key for opening the first lock of the third conversion cabinet 500 is B, G, J, K, L, the key for opening the second lock of the first conversion cabinet 100 is C, F, J, M, N, the key for opening the second lock of the second conversion cabinet 300 is D, I, K, N, o, the key to open the second lock of the third switch cabinet 500 is E, H, M, L, O, the key to open the first contact cabinet 200 is A, B, D, E, F, J, M, N, and the key to open the second contact cabinet 400 is B, E, H, G, J, K, M, O.

Specifically, the total number of keys is thirty-one, specifically, two a, three B, one C, two D, three E, two F, two G, two H, one I, three J, two K, one L, three M, two N, and two O.
