Abstract

The invention discloses a box-type substation safety door control device and method. The device mainly comprises a box door which is provided with an electromagnetic safety lock; the electromagnetic safety lock comprises an armature which is arranged on the box body in a sliding mode, and the upper end of the armature is connected with the box body through a spring; the lower end of the armature is opposite to an iron core on the box body, a working coil is wound on the iron core, and the working coil is connected into a control circuit; one side of the armature is connected with the clamping column through a connecting rod, and the box door is correspondingly provided with a clamping ring; and when the working coil is powered on, the clamping column moves downwards and is clamped with the clamping ring to form a locking structure. According to the box-type substation safety door control device and method provided by the invention, external personnel can be prevented from opening the box door by mistake under the electrified condition, and the safety of the external personnel is ensured.

Description

technical field [0001] The invention relates to the field of distribution networks, in particular to a control device and method for a safety door of a box-type substation. Background technique [0002] The box-type substation is one of the most commonly used equipment in the distribution network. As a connecting device between the power grid and the user, its performance is the guarantee for the safe and stable operation of the distribution network. There are many electrical equipment in the box-type substation, and these equipment need regular or irregular maintenance. Due to the existence of high-voltage lines in the box-type substation, its operation safety is very important during maintenance. [0003] Considering the safety of operators, it is usually required that the box door cannot be opened when the box-type substation is powered on, and the box door can only be opened when the power is cut off for maintenance. At present, the box door of the box-type substation ...
