Abstract
An electric mechanism for a ground switch in a high-voltage switch cabinet comprises a main operating shaft, a manual operating shaft, a manual operation lock, a front-door locking travel switch, a travel switch, a circuit breaker, a handcart locking travel switch, an on/off force arm and a rear-door locking travel switch, which are mounted on a main shaft in sequence and driven through a low-speed motor; a transmission gear and a gear are respectively arranged on the main shaft and an output shaft of a low-speed motor, so as to form a gear transmission system; and the low-speed motor is interlocked with the main operating shaft through the gear transmission system. The utility model can realize true unattended operation and improve the reliability and the safety of a high-voltage switch system.
Description
Technical field
The utility model relates to a kind of high-tension switch cabinet earthed switch motor drive mechanism, belongs to electric equipment manufacturing technology field.
Background technology
For fail safe and the reliability that guarantees power supply unit, high voltage ground switch has a cover locking and an interlocking gear, and behind high-tension switch cabinet earthed switch circuit breaker breaking, handcart falls back on the experiment position, opens the ground connection cutter by the manual operation axle.Back door, Qianmen just can be opened on this basis, and can carry out operations such as various maintenances this moment.Because of the back door is provided with blocking mechanism, before the back door was not closed, high voltage ground switch can not be closed, and the back door can't not opened before same high voltage ground switch was opened.By with the circuit breaker cart blocking mechanism when circuit breaker cart during in the service position, high voltage ground switch can not be opened, circuit breaker cart can't enter the service position when high voltage ground switch is closed equally.Travel switch can show the functions such as position of high voltage ground switch.Have only when high voltage ground switch is opened by the Qianmen blocking mechanism, the Qianmen can be opened, and the Qianmen can't be closed when high voltage ground switch is closed equally, and this moment, circuit breaker cart can't enter cabinet.When high voltage ground switch was opened, shell fragment ejected automatically and covers the manual operation axle, prevents misoperation by the manual operation blocking mechanism.As can be seen in the whole operation process by manually finishing, this makes the many items that comprise safety problem etc. be subjected to artificial limitation to a great extent.Because manual operation gets involved, be difficult to realize real unattended operation fully automatic system simultaneously.
The applicant is once by long-term production and research, at above defective, developed a kind of novel " high-tension switch cabinet earthed switch motor drive mechanism ", guaranteeing outside original operating function, the traditional power supply unit fail safe and reliability, it is chain to have increased electrical equipment, can carry out straighforward operation, realize the unattended operation system.National patent has been applied for and obtained to this technology
The utility model content
The purpose of this utility model is that a kind of novel high-tension switch cabinet earthed switch motor drive mechanism is provided again, to enlarge the practical range of this technology.
High-tension switch cabinet earthed switch motor drive mechanism described in the utility model, comprise operation axis, manual operation axle, manual operation locking, Qianmen locking travel switch, travel switch, circuit breaker cart locking travel switch, the on/off switch arm of force, back door locking travel switch, and be installed on the main shaft successively, drive by slowspeed machine, travelling gear and gear are set respectively on main shaft and the low speed electric motor output axle, form gear train assembly, make slowspeed machine and operation axis interlock by this gear train assembly.
The utility model can be realized real unattended operation, has improved the reliability and the fail safe of system.
