Load switch for magnesium electrolysis

Abstract

The invention discloses a load switch used for a rated voltage of 30VDC and a rated current of 6KA, and used for cell shut-down and start-up for magnesium electrolysis (called as load switch for short below), which belongs to the technical field of direct-current switching devices. The load switch is composed of the parts of a main switch, a drive motor, an air-type arc extinguishing system and the like. The switch adopts a structure with a single-pole hard-bar and soft connection, the single-pole hard-bar is used for mechanical fixed installation, and the soft connection is used for installation tolerance adjustment; the main touch system of the main switch adopts a conical structure, thus facilitating a bearing current to reduce a voltage drop; the operation mechanism of the main switch is used for driving a cam rotation mechanism by virtue of a hexagonal shaft, thus greatly simplifying the operation mechanism; the air-type arc extinguishing system is designed and installed on the hard copper bar of the main switch, and a certain time sequence of the main switch is ensured by virtue of an eccentric wheel installed on the hexagonal shaft, thus greatly prolonging the service life of the switch. According to the load switch, the cell shut-down and start-up working for magnesium electrolysis in case of no power-off is solved, and the effects of saving energy and reducing consumption, and improving product quality are remarkable.

Description

technical field [0001] The invention relates to a charge switch, in particular to a load switch (hereinafter referred to as a load switch) used for stopping and slotting magnesium electrolysis, which belongs to the technical field of DC switching appliances. Background technique [0002] During the production process of the charge switch, one or more slots often need to be short-circuited or disconnected according to production requirements. The traditional production process of the charge switch adopts the method of manual operation. The manual operation method is generally divided into two types. One is to use a copper rod to directly short the fracture. Potential safety hazards; another is to use American electrolytic pneumatic switches for derating, but special installation of pneumatic pipelines is required, which has high investment costs, high maintenance costs, and pneumatic pipelines are easy to corrode. [0003] In view of the deficiencies in the above-mentioned t...
