Intelligent isolating switch capable of being monitored on line

Abstract

The invention discloses an intelligent disconnecting switch capable of being monitored on line, which is characterized by comprising a base, and insulators are fixedly arranged at the two ends of the base; the upper end of the insulator is provided with a sealing cavity, a static contact is fixedly arranged in the sealing cavity, and one side of the sealing cavity is provided with an opening into which the conductive strip can be inserted; the knife switch is arranged above the insulator and is hinged with the insulator, and a moving contact corresponding to the static contact is arranged below the knife switch; the monitoring device is arranged on one side of the insulator, and the monitoring device comprises a shell, and a current transformer, a power supply module and a monitoring module which are arranged in the shell. Compared with the prior art, the intelligent isolating switch has the following advantages: on one hand, the intelligent isolating switch realizes a fully-closed structure of dynamic equipment, and a product does not have any exposed electrified body; the short circuit problem caused by ice, snow, rainwater, strong wind, birds and beasts and the like is solved; on the other hand, the current magnitude and the operating state and temperature of the isolating switch can be accurately and remotely acquired through the monitoring device, and the requirements of a transparent power grid and ubiquitous power internet of things can be met.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to an intelligent isolation switch that can be monitored online. Background technique [0002] The main function of the isolation switch is to form an obvious disconnection point in the circuit, which is generally used for isolating the power supply, switching off operation, or turning on and off small current circuits. In outdoor AC 50~60Hz and rated voltage 6~10kV power distribution system, the enclosed disconnect switch can be used directly as power isolation. Therefore, the outdoor AC high voltage enclosed disconnect switch is one of the main equipment in the outdoor AC high voltage distribution system. . [0003] The Chinese Patent Publication No. CN110212644A discloses a system and method for monitoring the working state of an isolating switch, including a controller and a state monitoring device; the state monitoring device includes an image acquisition device, an el...

Problems solved by technology

[0004] However, the above technical solutions cannot obtain functions such as current magnitude and operating temperature monitoring of isolating switches, and cannot meet the needs of transparent power grids and ubiquitous power Internet of Things

However, the high-voltage isolating switch has been working under the condition of high voltage and high current. Even if the contact resistance increases slightly, the power loss of the contact will increase and generate heat. If the heat is not treated in time, the equipment may be melted down.
