Problems solved by technology

However, the contact can only be connected to the closing resistor when closing, which can avoid the closing overvoltage, but cannot avoid the opening overvoltage phenomenon.
Japan is an early country in the study of UHV circuit breakers, but mainly adopts the GIS scheme, which must be equipped with more than two operating mechanisms and UHV insulating bushings, which has low reliability and is difficult to process.

Embodiment Construction

[0035] like figure 1As shown, the double-break combined column UHV double-speed breaking circuit breaker of the present invention includes an insulating support and a breaking device installed on the top of the insulating support, and a voltage equalizing capacitor is connected in parallel to the breaking device. The breaking device includes two breakers B1 and B2 connected in series, each of which is connected in parallel with a set of equalizing capacitors C1 and C2, and the function of the equalizing capacitors C1 and C2 is to distribute the voltage to two Breaker B1, B2. The insulating posts include side insulating posts supported on the breakers B1 and B2 respectively and intermediate insulating posts supported on the common ends of the two breakers; each insulating post and the outer surfaces of the breakers B1 and B2 have insulating magnetic rings. like figure 2 As shown, the side insulating pillars include three side supporting insulating pillars A1 arranged in a tr...

Description

technical field [0001] The invention relates to a circuit breaker used in power equipment, in particular to a double-break combined column ultra-high voltage double-speed breaking circuit breaker. Background technique [0002] Circuit breakers are often used in power equipment switches. When used as high-voltage or ultra-high-voltage circuit breakers, the faster the breaking speed and the shorter the time, the better, because it is easy for the moving contacts and static contacts of high-voltage electrical equipment to be close to each other. When an arc is generated, the faster the breaking speed, the shorter the arc generation time and the less damage to the equipment. In addition, a long-distance live line with no load or a small load will form a very high operating overvoltage in the power grid when opening and closing. If these overvoltages are not limited by a special device, over-insulation measures must be taken in the UHV grid, which will inevitably increase the co...
