Intelligent column switch and control system

Abstract

The invention relates to an intelligent column switch and control system, and belongs to the electric power automation technical field; the intelligent column switch comprises a housing, a switch bodyarranged in the housing in an insulated mode, and a control terminal; the control terminal comprises an information acquisition device, a switch lock, a sampling circuit, a power supply circuit, a controller, a wireless communication unit, and an alarm device; the controller is used for preprocessing a wireless signal received from the wireless communication unit, thus obtaining preprocessed information, and determining whether the preprocessed information contains the first information or not; if yes, the first information is coupled with a pre-stored ID information database; if the couplingis finished, operations corresponding to a control order carried by the wireless signal are executed. The intelligent column switch can remotely send the control order according to manager demands, thus opening or closing, adjusting and calibrating parameters, simplifying field maintenance work load, and maximumly reducing the operation safety troubles.

Description

technical field [0001] The invention belongs to the technical field of electric power automation, and in particular relates to an intelligent pole-mounted switch and a control system. Background technique [0002] In the domestic distribution network, a certain number of pole-mounted switches are installed on the overhead line. In the routine maintenance process, the traditional switch on the pole requires the maintenance personnel to climb the pole to the switch on the pole to open and close the switch. For the current intelligent pole switch, although it is equipped with a control box, considering the convenience and safety of local operation, the control box is generally far away from the installation position of the switch. The power supply of the control box is also connected to the control box by one or two voltage transformers through cables to realize power supply and voltage data collection. However, maintenance personnel still need to climb the pole to the contro...

However, maintenance personnel still need to climb the pole to the control box of the switch on the pole to perform related operations

Moreover, this structure forms many different independent components and accessories such as the switch body, control box, power supply PT, and connecting cables after processing and manufacturing, which makes the installation and debugging work not only heavy and complicated, but also prone to errors, causing equipment damage. Delays in construction lead to loss of power supply

In addition, the operation of this type of pole-mounted switch is more complicated, and it is necessary to ensure that the equipment is effectively grounded, which poses serious safety hazards. Therefore, it is urgent to develop a non-contact, high-safety wireless remote control device that can be easily read The real-time current data of the power grid and various state quantities of the switch on the column can also set the parameters of the switch on the column, and can perform remote opening and closing operations, simplifying the workload of on-site maintenance and minimizing operational safety hazards
