Detailed Description
In order that the objects, aspects and advantages of the present invention will become more apparent, the invention will be further described in detail with reference to the following detailed description and accompanying drawings.
It should be noted that all expressions of "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name or different parameters, and it is understood that "first" and "second" are merely for convenience of description and should not be construed as limiting the embodiments of the present invention, and that the directions and positions of the terms, such as "up", "in", "down", "before", "after", "left", "right", "inside", "outside", "side", etc., in the present invention are only referred to the directions and positions of the attached drawings, and therefore, the directions and positions are used for explaining and understanding the present invention, and are not used for limiting the subsequent embodiments of the present invention.
As shown in the figure, the outdoor high-voltage vacuum circuit breaker provided based on the above purpose comprises a switch cabinet 1 arranged outdoors for accommodating the vacuum circuit breaker, a door body 2 arranged on the switch cabinet 1 and a blocking bolt 5 placed on the inner side wall of the switch cabinet 1 in peacetime. The vacuum circuit breakers in the switch cabinet 1 are divided into an upper stage and a lower stage, an upper stage vacuum circuit breaker is respectively connected with all lower stage vacuum circuit breakers in series, all the lower stage vacuum circuit breakers can cut off current after the upper stage vacuum circuit breakers are disconnected, the upper stage vacuum circuit breakers are connected with separating brakes for controlling whether circuits are disconnected or not in series, and the separating brakes are provided with through holes matched with blocking bolts 5. When the subordinate vacuum circuit breaker needs to be overhauled, the opening in series connection with the superior vacuum circuit breaker is firstly disconnected, the opening exposes the through hole on the opening, and then the blocking pin 5 is inserted into the through hole, so that the opening is prevented from moving again under the action of external force, and the superior vacuum circuit breaker is opened.
