Insulated discharge rod for capacitor

Abstract

The invention discloses an insulating discharge rod for a capacitor. Maintenance personnel can discharge a capacitor under the condition that an insulating sheath is not dismounted. The insulating discharge rod comprises at least one discharge part; each discharge part comprises two discharge contacts, two discharge terminals, a conductive steel plate and a wire; the discharge terminals are arranged at one ends, far away from the conductive steel plates, of the discharge contacts; the length of the discharge contacts is larger than the depth of the insulating sheath of the capacitor, and the wires are connected with the ground and used for releasing charges. When discharge is required, the discharge contacts extend into the insulating sheath of the capacitor, the width of the discharge contacts ensures that the discharge contacts can extend into the insulating sheath, and the length of the discharge contacts ensure that the discharge terminals can be in contact with the electrical terminal of the capacitor, thereby realizing electrical conduction. The discharge terminals conduct charges to the conductive steel plates, the conductive steel plates are connected with the wires, the wires are connected with the ground, the charges in the capacitor are released to the ground, and the function that the capacitor can be discharged without detaching the insulating sheath of the capacitor is achieved.

Description

Technical field [0001] The invention relates to the field of electrical auxiliary equipment, in particular to an insulated discharge rod used for capacitors. Background technique [0002] Capacitors play an important role in substations, mainly used to store electrical energy and improve the power factor of substations. When the substation needs to be overhauled, in order to ensure the safety of the overhaul personnel, the substation will be powered off to prevent the overhaul personnel from getting an electric shock; due to the large amount of electric charge stored in the capacitor, a great safety hazard is caused, and a discharge rod is usually used to remove the capacitor. The charge in the battery is completely discharged. [0003] Usually, maintenance personnel are required to ground the discharge rod, and then simultaneously contact the discharge rod with the two polar terminals of the capacitor to achieve the purpose of discharge. However, the two terminals of the current...
