Abstract
The invention provides a mechanical interlocking device of a bottom plate. When a right-side breaker is switched on, a right-side push rod is downward and a movable rod rotates in a clockwise direction; a left-side push rod is upwards ejected under the push of a left-side support and is clamped between a movable contact and a static contact of a left-side breaker, so that the left-side breaker cannot be switched on; on the contrary, the left-side breaker is switched on, the left-side push rod is downward and the movable rod rotates in an anticlockwise direction; the right-side push rod is upwards ejected under the push of a right-side support and is clamped between the movable contact and the static contact of the right-side breaker, so that the right-side breaker cannot be switched on; therefore, the requirements on switching on one breaker and switching off the other breaker are met by the mechanism. Once one power supply breaks down, the power can be supplied to two load lines by a normal (fault-free) power supply at the same time; meanwhile, electric shock or blackout accidents caused by incorrect man-made operations are avoided.
Description
Technical field
The present invention relates to a kind of base plate mechanical interlocks and method.
Background technology
The requirement that do not have a power failure when adapting to line powering, duplicate supply (the normal electrical network source adds the emergency network power supply, and the normal electrical network source adds emergency diesel generator) conversion equipment uses more and morely now.In order to prevent that two mains switches from closing a floodgate simultaneously, causes serious consequences such as short circuit.Mechanical interlocking must be set, or possess machinery and electric interlocking installation simultaneously.These adaptable mains switches of interlocking are contactor, on-load switch or circuit breaker.Because circuit breaker has defencive functions such as overload, short circuit, under voltage, it replaces contactor etc. gradually, becomes main mains switch.
In addition; For solving two separately to its power supply of electric; In case when having a power supply to break down, can be by the power supply of normal (fault-free) to two loaded lines powerup issues simultaneously, and for need of work; Avoid because of electric shock or power outage take place in artificial misoperation, these all require circuit breaker that the self-locking measure is arranged.
Summary of the invention
The technical problem that the present invention will solve provides a kind of auto-lock function that has, and can avoid shocking by electricity or the base plate mechanical interlocks of power outage.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: comprise the installation base plate, and be arranged on left side circuit breaker and the right side circuit breaker of installing on the base plate; Circuit breaker below, said left side is provided with the left side push rod; Circuit breaker below, said right side is provided with the right side push rod, and said installation base plate is provided with the moving bar that a highstrenghtpiston processes, and moving bar two ends are provided with the left side support and the right side is supported; Said left side push rod and left side are supported and are connected, and said right side push rod and right side are supported and connected.
Another technical problem that the present invention will solve provides a kind of auto-lock function that has, and can avoid shocking by electricity or the base plate mechanical interlocking method of power outage.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: when the breaker closing of right side, the right side push rod is downward; Moving bar is made clockwise direction and is rotated; The left side push rod up pushes up under the promotion of left side support, is stuck between the dynamic and static contact of left side circuit breaker, makes it and can't close a floodgate; Otherwise, the left side breaker closing, the left side push rod is downward; Moving bar rotates counterclockwise, and supports under the promotion on the right side, and the right side push rod is stuck between the dynamic and static contact of right side circuit breaker; Make it and to close a floodgate, realize a breaker closing, the requirement that another must separating brake with this mechanism.
Base plate mechanical interlocks of the present invention and method in case when having a power supply to break down, can be supplied power simultaneously to two loaded lines by the power supply of normal (fault-free), have been avoided because of artificial misoperation electric shock or power outage taking place simultaneously.

Embodiment
In the present embodiment, as shown in Figure 1, comprise base plate 1 is installed; And be arranged on the left side circuit breaker of installing on the base plate 12 and right side circuit breaker 3, and circuit breaker 2 belows, said left side are provided with left side push rod 4, and circuit breaker 3 belows, said right side are provided with right side push rod 5; Said installation base plate 1 is provided with the moving bar 6 that a highstrenghtpiston processes; Moving bar 6 two ends are provided with left side support 7 and support 8 with the right side, and said left side push rod 4 supports 7 with the left side and connects, and said right side push rod 5 and right side are supported 8 and connected.
When right side circuit breaker 3 closed a floodgate, right side push rod 5 was downward, and moving bar 6 is made clockwise direction and rotated, and left side push rod 4 up pushes up under the promotion of left side support 7, is stuck between the dynamic and static contact of left side circuit breaker 2, makes it and can't close a floodgate; Otherwise left side circuit breaker 2 closes a floodgate, and left side push rod 4 is downward; Moving bar 6 rotates counterclockwise, and supports under 8 promotions on the right side, and right side push rod 5 is stuck between the dynamic and static contact of right side circuit breaker 3; Make it and to close a floodgate, realize a breaker closing, the requirement that another must separating brake with this mechanism.
Base plate mechanical interlocks of the present invention and method in case when having a power supply to break down, can be supplied power simultaneously to two loaded lines by the power supply of normal (fault-free), have been avoided because of artificial misoperation electric shock or power outage taking place simultaneously.
Below the present invention is done a detailed description, the above is merely the present invention's preferred embodiment, when can not limiting practical range of the present invention, promptly allly does impartially to change and modify according to the application's scope, all should still belong in the covering scope of the present invention.
