Embodiment Construction
[0035] The following is attached Figure 1-5 The application is described in further detail.
[0036] The embodiment of the present application discloses a modular permanent magnet high voltage vacuum circuit breaker. refer to figure 1 , figure 2 , the modular permanent magnet high-voltage vacuum circuit breaker includes an insulating frame 1 for placing inside the housing of the high-voltage vacuum power distribution device. The insulating frame 1 includes a hollow base 10 and a plurality of mounting bases 101 arranged in sequence. The number of mounting bases 101 can be increased or decreased according to actual needs, and the number of mounting bases 101 in this embodiment is three groups. The lower ends of the three sets of mounting bases 101 are fixedly installed in the base 10 , and the upper ends of the mounting bases 101 protrude from the base 10 .
[0037] Such as figure 2 , image 3 As shown, three groups of control mechanisms 2 are installed in the insulati...

The invention discloses a modular permanent-magnet high-voltage vacuum circuit breaker, which comprises an insulating frame placed in a high-voltage vacuum power distribution device shell, wherein the insulating frame is internally provided with a plurality of groups of mutually independent control mechanisms; and each control mechanism comprises a first socket and a second socket which are used for being matched with an external circuit in an inserted mode, a plurality of sets of permanent magnet mechanisms in linkage with the corresponding control mechanisms are further arranged in the insulation frame, and the permanent magnet mechanisms are used for switching on and off power supply loops of the corresponding control mechanisms. According to the modular permanent-magnet high-voltage vacuum circuit breaker, the layout of the vacuum circuit breaker is optimized, so that the internal part of the vacuum circuit breaker is more reasonable; and when the control mechanisms and / or the permanent magnetic mechanisms located in the high-voltage vacuum power distribution device shell needs to be maintained, the whole insulation frame is moved out of the high-voltage vacuum power distribution device shell, and therefore the control mechanisms and / or the permanent magnetic mechanisms can be maintained more conveniently and rapidly.
Description
technical field [0001] The invention relates to the field of circuit breakers, in particular to a modular permanent magnet high-voltage vacuum circuit breaker. Background technique [0002] The power enterprise is a key industry in my country, which has a very important influence on people's life and production. In order to ensure the stability, safety and reliability of the power system operation, it is necessary to protect and disconnect the generators in the power system. It is necessary to conduct research between the two breakers, and a suitable coordination scheme is needed between the two to promote the normal operation of the power grid. For most of the current outdated circuit breakers, it is obviously difficult to meet the current power operation requirements, and there is still a need for maintenance. Investing a lot of money will not only increase the economic burden if it continues like this, but also the power operation will not be effectively guaranteed. [000...
