Abstract

The invention relates to the technical field of electrical safety production and discloses a safety interlocking program device. A program board is arranged in a housing through a sliding mechanism, an incoming line lock and at least two outgoing line locks are mounted to a lock cover of the housing, a playground-shaped first elongated hole is formed in the program board and in the position corresponding to the incoming line lock, a playground-shaped second elongated hole is formed in the program board and in the position corresponding to each outgoing line lock, the path of motion of each outgoing line lock from an unlocked state to a locked state is a 90-degree arc, an arc hole is formed in the program board and in the position corresponding to the 90-degree arc, and the arc hole is communicated with the second elongated holes. After the device is assembled, a bolt of the incoming line lock is inserted into the first elongated hole, and a bolt of each outgoing line lock is inserted into the respective second elongated hole or the arc hole. According to the invention, by operating the incoming line lock and the outgoing line locks, applicationprogram of a key conforms to the requirements for electrical safety working regulations.

Description

technical field [0001] The invention relates to the technical field of electrical safety production, in particular to a safety locking program device. Background technique [0002] Power plants, substations, substations, distribution substation isolation switches, and grounding switches have strict operating procedures. If such procedures are only followed by humans, mistakes will inevitably occur, resulting in misoperation, short circuit, equipment damage or personal accidents caused by electric shock. Therefore, the blocking measures to prevent misoperation of power switches are mandatory requirements of national and international electrical product standards. The current anti-misoperation measures include electric locks, mechanical linkage locks, and program locks that can be toggled by the lock cylinder. Realization; the lock cylinder can be dialed, and the program lock is sometimes invalid due to the displacement of the lock cylinder, and it is easy to misuse the manua...
