Problems solved by technology

At present, the 12kV AC vacuum circuit breaker uses a general-purpose resistor divider product, which has low precision and poor stability, and the general-purpose resistor divider product only has a single closing and closing function. The function of breaking is just an actuator in the complete circuit, and various parameters of the circuit operation as well as closing, opening and protection command signals are provided by external supporting components.

Embodiment Construction

[0008] Referring to accompanying drawing 1, Fig. 1 is the three-dimensional partial cut-away structural view of the present invention. The specific method of the present invention is as follows: first cut the ceramic substrate, make printed resistance wire 5 and connection terminal 1, signal terminal 2, and ground terminal 3 on the ceramic substrate 4, and sinter at 800 ° C, and then print green on the surface of the resistance. For the protective layer 6, the black protective layer 7 is printed after laser trimming, and sintered at a high temperature of 600°C. After aging the voltage dividing resistor at high temperature, solder the 12kVAC terminal 1, 5VAC signal terminal 2, and ground terminal 3 with high-temperature soldering materials. Finally, the APG process is used to wrap the silicone rubber 8. In order to solve the high voltage creepage and safety insulation, a unique silicone rubber CNC injection molding process is adopted to wrap the resistor divider of the ceramic...

Description

technical field [0001] The invention belongs to the technical field of electric power engineering, and in particular relates to the improved design and manufacture of a 12kV solid-sealed resistor divider used in an intelligent AC vacuum circuit breaker. Background technique [0002] The 12kV AC vacuum circuit breaker is a mechatronic product, widely used in the indoor complete set of switchgear with a voltage level of 12kV and below in the power system. The intelligentization and miniaturization of the circuit breaker body is the development direction of the circuit breaker. Therefore, the technology of designing new resistor dividers and current transformers and integrating them with circuit breakers has become the focus of research and development of intelligent circuit breakers, and the quality requirements for resistor dividers are relatively high. At present, the 12kV AC vacuum circuit breaker uses a general-purpose resistor divider product, which has low precision and ...
