Comprehensive network misoperation-preventive locking device

Abstract

The invention discloses a comprehensive network misoperation-preventive locking device. The device comprises a shell, a locking rod and a locking pin, wherein the locking rod and the locking pin are installed on the shell. A locking groove is formed in the locking rod. A locking head is arranged at the first end of the locking pin. The second end of the locking pin is connected with a spring. Meanwhile, the device is provided with a local unlocking mechanism and a remote unlocking mechanism. The remote unlocking mechanism locks the locking pin when the remote unlocking mechanism is in a locked state. The remote unlocking mechanism is connected with a remote control terminal through a network. After the remote control terminal transmits an unlock command, the remote unlocking mechanism unlocks the locking pin. The local unlocking mechanism controls the locking pin to slide through an anti-mistaken-unlock key, the locking head is disengaged from the locking groove, and the locking rod is unlocked. By means of the device, management of combining local control and remote control on the locking device is achieved, the operation safety of equipment is prevented from being influenced by on-site mistaken unlocking or mixing-up of locks after unlocking, and safety operation of important equipment in a power system is protected.

Description

technical field [0001] The invention relates to a locking device for substations, power plants and other equipment, in particular to a device with reliable locking applied in substations, power plants and other occasions. Background technique [0002] There are a lot of equipment in the power industry. If the operation is careless or mishandled, the equipment will be damaged in the slightest, and the personal safety will be caused in the serious one. Therefore, such equipment is usually locked with locks with anti-misoperation locking function. Usually, a simple padlock is used for locking. For equipment with simple functions, this locking method can ensure the safety of the equipment. For important equipment, such as circuit breaker switches on high-voltage switch cabinets, if the lock is opened by mistake , it may be related to the safe operation of large-scale equipment such as main transformers. Therefore, the locking of such equipment is particularly important, and the ...

Problems solved by technology

Usually, a simple padlock is used for locking. For equipment with simple functions, this locking method can ensure the safety of the equipment. For important equipment, such as circuit breaker switches on high-voltage switch cabinets, if the lock is opened by mistake , it may be related to the safe operation of large-scale equipment such as main transformers. Therefore, the locking of such equipment is particularly important, and the routinely used anti-misoperation method is to hang a padlock near the operating handle of this type of equipment, and the padlock must be opened when it is necessary to operate. , in the actual operation process, due to problems such as mis-opening of locks and misplacement of locks after unlocking, the reliable operation of the equipment cannot be fully guaranteed, which affects the safe operation of substation equipment and personal safety. It is necessary to invent a new type of anti-misoperation locking The device adds further unlocking restrictions on the basis of the conventional anti-misoperation workflow, which can ensure that a single misoperation will not directly open the lock, realizing the high security of the locked lock
