Description

Indicating device Technical Field The utility model relates to the technical field of isolating switch indicating devices, in particular to an 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 column opening circuit breaker and the isolating switch are provided with switch position indicating devices which are matched with the isolating switch for use, so that the safety of maintenance and operation is ensured. 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. To meet the "five-guard" safety requirements of circuit breakers and disconnectors, the mechanical and electrical interlocking of the circuit breaker and disconnector is typically configured. The circuit breaker can only be operated if the position of the disconnector is correct and the mechanical and electrical interlocks are unlocked simultaneously. In general, the two states of opening and closing are significantly changed, but the accuracy of the position angle is not required. In the mechanical transmission process, the position indication and the actual separation and combination position of the isolating switch can be deviated due to transmission loss, or the position indication device can not accurately indicate the switch position due to the damage of a transmission part, and maintenance personnel can face a larger challenge and is difficult to quickly find when positioning the problem due to the fact that the isolating fracture can not be directly observed, and meanwhile, the problem of certain potential safety hazard also exists.
