Abstract
Powered mating switch appliance field the utility model discloses a kind of power network, particularly a kind of breaker, including breaker body, fixed pivot is provided with the bottom outer surface of breaker body, lever arm is hinged with the fixed pivot, the side of the lever arm is connected with isolator operating mechanism, the connecting rod of the basal surface through breaker body is connected with its opposite side, the connecting rod can by lever arm drive realization move up and down, and the connecting rod end side connect breaker body tripping operation drive rod.The technical problem of " simplify breaker structure " is which solved, it possesses and ensure that disconnecting switch not on-load operation, and overall structure is simple, the advantages of operational stability is good.
Description
Technical field
The utility model is related to a kind of power network to power mating switch appliance field, particularly a kind of breaker.
Background technology
Should be possessed according to national standard requirement high-tension switch cabinet prevents from dividing by mistake, closes breaker, prevents on-load point, conjunction isolation
Switch（Or stab contact）, prevent disconnecting link with ground（Or ground wire）Power transmission, prevents charged co-grounding switch（Or hanging earthing conductor）
Deng " five prevent " function.
At present, the realization of " five prevent " mechanical interlocking of China 12kV fixed switching cabinets is used by breaker mostly
Two sets of mechanical drivings being connected with switch cabinet grounding switch and isolator operating mechanism respectively of upper setting, realize when operation
During JS mechanisms, one of which is realized linking breaker open operation, and another set is used to prevent manually operated breaker closing.But
It is that the foregoing breaker for carrying mechanical driving of the prior art has complex structure, maloperation incidence grade one high
Serial drawback.
Utility model content
The purpose of this utility model is that to provide a kind of structure to solve above-mentioned the deficiencies in the prior art relatively simple
Breaker.
To achieve these goals, a kind of breaker designed by the utility model, including breaker body, in breaker
The bottom outer surface of body is provided with fixed pivot, is hinged with lever arm on the fixed pivot, the side of the lever arm with every
It is connected from switch operating mechanism, the connecting rod of the basal surface through breaker body is connected with its opposite side, the connecting rod can be by
Lever arm drive realization move up and down, and the connecting rod end side connect breaker body tripping operation drive rod.
A kind of above-mentioned breaker, interlocking mechanism is positioned over breaker bottom in its structure, for breaker once and two
Secondary terminal installs wiring does not have any influence, using a fixed pivot, and with the principle of lever, by one end of lever arm with
The tripping operation drive rod of breaker is connected, and the other end is connected with isolator operating mechanism, as long as isolator operation drivening rod,
Make circuit breaker trip, it is ensured that disconnecting switch not on-load operation, its overall structure is simple, good operating stability.
A kind of breaker that the utility model is obtained, it ensure that disconnecting switch not on-load operation, and overall structure
Simply, operational stability is good, its fixed breaker for being applied to all kinds of different models and all kinds of isolator operating mechanisms, can
The need for meeting different user, as long as adjusting length to connecting rod.
Brief description of the drawings
Fig. 1 is that embodiment 1 provides a kind of structural representation of breaker；
Fig. 2 is the structural representation that embodiment 1 provides interlocking mechanism in a kind of breaker.
In figure：Breaker body 1, fixed pivot 2, lever arm 3, connecting rod 4, tripping operation drive rod 5.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Embodiment 1：
As depicted in figs. 1 and 2, a kind of breaker provided in the present embodiment, including breaker body 1, in breaker
The bottom outer surface of body 1 is provided with fixed pivot 2, and lever arm 3, the side of the lever arm 3 are hinged with the fixed pivot 2
It is connected with isolator operating mechanism, the connecting rod 4 through the basal surface of breaker body 1, the company is connected with its opposite side
Bar 4 can drive realization to move up and down by lever arm 3, and the tripping operation of the end side connection breaker body 1 of the connecting rod 4 drives
Bar 5.
A kind of above-mentioned breaker, interlocking mechanism is positioned over breaker bottom in its structure, for breaker once and two
Secondary terminal installs wiring does not have any influence, using a fixed pivot 2, and with the principle of lever, by one end of lever arm 3
It is connected with the tripping operation drive rod 5 of breaker, the other end is connected with isolator operating mechanism, as long as isolator operation drives connecting
Bar 4, makes circuit breaker trip, it is ensured that disconnecting switch not on-load operation, its overall structure is simple, good operating stability.
