Detailed Description
The above objects, features and advantages of the present invention will be more clearly understood and the present invention will be explained in more detail with reference to the accompanying drawings 1 to 4 and the detailed description thereof.
The mechanical interlocking device for the middle-placed switch cabinet adopted by the embodiment comprises an upper mounting bracket 2 with a shaft hole 21, a lower mounting bracket 3 with a shaft hole 31 and a fan-shaped interlocking baffle plate 1 with a fixing shaft 11, wherein one end of the fixing shaft 11 is mounted in the shaft hole 21 of the upper mounting bracket 2, the other end of the fixing shaft 11 is mounted in the shaft hole 31 of the lower mounting bracket 3, the upper mounting bracket 2 and the lower mounting bracket 3 move in a handcart guide rail 5 on a switch cabinet body 4, and the fan-shaped interlocking baffle plate 1 swings around the fixing shaft 11 to limit a main circuit breaker handcart 6 and a standby circuit breaker handcart 7 from entering a working position simultaneously.
When the main circuit breaker handcart 6 is pushed to a working position, the fan-shaped interlocking baffle plate 1 rotates around the fixed shaft 11 to the spare circuit breaker handcart 7, the roller 61 of the main circuit breaker handcart 6 abuts against the fan-shaped interlocking baffle plate 1, the main circuit breaker handcart 6 is in the working position, the fan-shaped interlocking baffle plate 1 cannot rotate at the moment, and therefore the spare circuit breaker handcart 7 is blocked, the spare circuit breaker handcart 7 cannot be pushed to the working position, otherwise, when the main circuit breaker handcart 6 is withdrawn, the spare circuit breaker handcart 7 can be pushed to the working position, and the main circuit breaker handcart 6 cannot be pushed to the working position, so that the mechanical interlocking of main use, spare use and two-in-one is realized.
The working principle of the mechanical interlocking device of the middle-positioned switch cabinet in the embodiment is as follows:
when two switch cabinets supply power to an important load, only one switch cabinet is allowed to be put into operation, the other switch cabinet is used as a spare, namely, in the two switch cabinets, only one circuit breaker handcart can be pushed to a working position, and the other circuit breaker handcart is used as a spare to be positioned at a test position. Before the switch cabinet handcart is put into operation, two switch cabinet handcarts are simultaneously at a test position, the fan-shaped interlocking baffle is at an intermediate position in a free state, when a main circuit breaker handcart is pushed to a working position from the test position, after the main circuit breaker handcart travels for a certain distance, the main circuit breaker handcart travels to impact the fan-shaped interlocking baffle, the fan-shaped interlocking baffle rotates around a fixed shaft center to the direction of a standby circuit breaker handcart, the main circuit breaker handcart travels to the working position, the circuit breaker is switched on, and the switch cabinet is put into operation. The spare circuit breaker handcart is limited by the fan-shaped interlocking baffle plate and cannot be pushed to a working position, and safe operation is guaranteed. When the main breaker handcart needs to be overhauled, the working breaker is swung out to a test position after being separated, the fan-shaped interlocking baffle plate is restored to be in a free state and is in an intermediate position, and the standby breaker handcart can also be swung into the working position to realize operation.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
