The invention discloses a five-protection interlocking operation mechanism for a switch cabinet, and relates to a mechanism device for a high-voltage switch cabinet for operating a disconnecting switch and a grounding switch. The five-protection interlocking operation mechanism comprises an operation panel, a middle partition, a rear fixed plate and two groups of operating large shafts, wherein the operation panel, the middle partition and the rear fixed plate define a first chamber and a second chamber; an upper indicator plate, a lower indicator plate, an upper interlocking panel and a lower interlocking panel are arranged in the first chamber; an upper limiting crank arm and a lower limiting crank arm are located in the second chamber; an upper driving crank arm and a lower driving crank arm are arranged at the tail ends of the two groups of operating large shafts separately; a breaker interlocking lever runs through the middle partition and the rear fixed plate; an interlocking hook plate is arranged at the front end of the breaker interlocking lever; a locking guide rail bending plate is welded on the middle partition; an overhead bolt is arranged on one operating large shaft; and a lifting baffle plate runs through the middle partition and the rear fixed plate. The five-protection interlocking operation mechanism is small in size, simple and reliable in operation, few in parts and complete in interlocking.
Description
technical field [0001] The invention relates to an operating mechanism for five-proof interlocking of a high-voltage switch cabinet, in particular to an operating mechanism. Background technique [0002] The high-voltage switchgear needs to meet the requirements of five-proof interlocking during operation, among which, it is necessary to prevent the opening and closing of the disconnector with load; The basic requirements for the five-proof interlocking of high-voltage switchgear are also the most complicated and difficult link in the five-proof interlocking. The isolating switch and the grounding switch are the two most used electrical appliances in the high-voltage switchgear. The isolating switch plays the role of isolating the power supply in the circuit, and the grounding switch grounds it when the primary circuit is powered off. When the isolating switch and the grounding switch are in the matching switchgear, they need to be operated with the matching circuit breaker...
