The invention provides an insulating cylinder applicable to circuit breakers at 3.6kV rated voltage and below. The insulating cylinder comprises a cylindrical body, an upper outlet hole and a lower outlet hole are arranged in the cylindrical body, and the upper outlet hole and the lower outlet hole are both open and arranged vertically; internal umbrella skirts of a whole-cycle periphery structure are arranged between insides of the upper and lower outlet holes, and external umbrella skirts of a semicircular structure and protruding out of the external circular surface are arranged between outsides of the upper and lower outlet holes; three sides of the top of the upper outlet hole are surrounded by insulation wall layers. Creepage distance is increased by the internal and external umbrella skirts, and pollution discharge level is improved obviously; both the upper and lower outlet holes are open, the aerodynamic principle is utilized effectively, gas circulation is quickened, heat is dissipated effectively, temperature rise is lowered, and service life is prolonged remarkably; insulating strength is heightened remarkably by the insulating wall layers at the top of the upper outlet hole. The insulating cylinder is applicable to products at 3.6kV rated voltage and below, small in structure, low in manufacture cost and convenient and simple to install.
Description
technical field [0001] The invention relates to the field of high and low voltage electrical appliances, in particular to an insulating cylinder suitable for circuit breakers with a rated voltage of 3.6kV and below. Background technique [0002] Most of the traditional insulating cylinders are used in power systems with rated voltages ranging from 12kV to 40.5kV. In recent years, the power supply system with a rated voltage of 3.6kV has sprung up rapidly, but there is no insulation cylinder designed for this voltage level in the corresponding industry, and the insulation cylinder with a rated voltage of 12kV is used instead. This not only costs too much, wastes materials, but also affects product quality. [0003] Therefore, in order to improve product quality and optimize cost, it is urgent to design an insulating cylinder with a rated voltage of 3.6kV that meets market demand. Contents of the invention [0004] The technical problem to be solved by the present inventio...
