Abstract

The invention relates to a switch cabinet and a control method for locking electric ground knife of the switch cabinet. The electric ground knife locking control method of the switch cabinet of the present invention: when the bus bar is electrified, the ground knife operating shaft is locked at the opening position by means of mechanical locking, and the control circuit of the electric drive mechanism of the electric ground knife is disconnected; When the busbar is powered off and needs to be grounded and switched on, the mechanical locking of the operating shaft of the ground knife is released, and the control circuit of the electric drive mechanism of the electric ground knife is turned on. With this control method, electrical locking can be realized simultaneously with mechanical locking, which prevents misoperation of electrical control and ensures the reliability and safety of switchgear operation.

Description

technical field [0001] The invention relates to a high-voltage switchgear, in particular to a switchgear and a control method for electric ground knife locking of the switchgear. Background technique [0002] With the demand for intelligent and unmanned operation in the electric power industry, more and more intelligent equipment is used in intelligent substations. a manifestation of. At present, the electric floor knives in the switchgear can realize electric opening and closing through remote intelligent control, but the simplicity of such control is easy to cause more misoperations. Higher requirements are put forward for its security. [0003] The more common switch cabinets currently on the market also have a locking structure for the ground knife operating shaft, such as the locking device disclosed in the Chinese patent with the authorized announcement number CN202711997U and the authorized announcement number CN202167781U about the ground knife operating shaft in t...
