Description

Switch indicating device Technical Field The utility model relates to the technical field of isolating switch indicating devices, in particular to a switch indicating device. Background In recent years, with the vigorous development of the power industry, the distribution switch realizes remarkable improvement in product structure and performance. As a core in electrical distribution products, pole-mounted switches have undergone significant product category and performance changes. Particularly, along with the mass production of the secondary fusion on-column switch, the intelligent level of the on-column switch is remarkably improved. In order to ensure the safe operation and maintenance of the product, the isolating switch is usually matched with the isolating switch. At present, most products adopt an external isolation fracture design, while part of products adopt an internal isolation fracture, so that the stability of the isolation fracture is improved, and the service life of the isolation fracture is effectively prolonged. For guaranteeing the steady operation and the safe maintenance of product, the column opening circuit breaker and isolator all are equipped with switch position indicating device to clearly show the switch position, ensure the security of maintaining and operation. The isolating break is not visible due to the structural nature of the built-in isolating switch. The exact position of the disconnector is completely dependent on the switch position indication means and the interlocking means with the circuit breaker. The circuit breaker can only be operated if the position of the disconnector is correct and the mechanical and electrical interlocks are unlocked simultaneously. The mechanical transmission system of the switch indication device is derived from the switch operating mechanism. In the traditional device, the movement is transmitted to the indicating component through the opening and closing actions of the operating component by utilizing mechanical transmission components such as gears and the like so as to realize position indication. In the mechanical transmission process, due to abrasion of gear transmission, deviation of the position indication and the actual separation and combination position of the isolating switch can occur, and the position indication device cannot accurately indicate the switch position due to damage of a transmission part.
