Abstract

The invention discloses a current transformer based on wireless communication technology networking, and relates to the technical field of electric power systems. The current transformer based on wireless communication technology networking comprises a current transformer, a primary winding and a secondary winding, wherein the primary winding and the secondary winding are wound on the current transformer. The secondary winding is electrically connected with the input end of a secondary current acquisition and conversion module, and the output end of the secondary current acquisition and conversion module is electrically connected with a wireless communication transmitting module through a processor I. The wireless communication transmitting module is in communication connection with a wireless communication receiving module. The wireless communication receiving module is electrically connected with the input end of a circuit restoration module through a processor II. The output endof the circuit restoration module is electrically connected with a measurement or protection circuit of measurement or protection equipment. According to the invention, the cost of secondary wiring ofthe current transformer is saved; and the problems that the current transformer has many wires, the transmission distance is long and signals are easy to interfere are solved.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a current transformer based on wireless communication technology networking. Background technique [0002] The current transformer is an important part of the power transmission and transformation equipment, and it is the contact element between the power primary system and the secondary system, and is indispensable in the power system. In order to meet the needs of measuring instruments, relay protection, circuit breaker failure judgment and fault filtering and other devices, 2~ 8 current transformers with secondary windings. [0003] At present, the signal transmission from the secondary winding of the current transformer to the measurement or protection equipment adopts the cable connection method, such as figure 1 shown. On-site wiring has the characteristics of many cables, long transmission distance, and the signal is susceptible to interference. There is no curren...
