Abstract
The utility model discloses an electric exclusive circuit of high pressure complete set cubical switchboard, it is including the secondary control loop of high pressure complete set cubical switchboard, secondary control loop on concatenate the shutting electro -magnet in micro -gap switch and the isolated wheelbarrow cabinet in proper order, micro -gap switch sets up on the back door of this high pressure complete set cubical switchboard. The utility model discloses convenient operation, the cost is lower, uses reliably.
Description
Technical field
The utility model relates to a kind of electric blocking circuit of high-voltage complete-set switch cabinet.
Background technology
Current high-voltage complete-set switch cabinet is all adopt separately mechanical latching mode, or electrical interlocks mode, and operation is comparatively complicated, and parts are more, and cost is higher.
Utility model content
Technical problem to be solved in the utility model is, provide a kind of electric blocking circuit of high-voltage complete-set switch cabinet, it is easy to operate, and cost is lower, uses reliable.
For solving the problems of the technologies described above, the electric blocking circuit of the high-voltage complete-set switch cabinet that the utility model provides, it comprises the secondary control loop of high-voltage complete-set switch cabinet, described secondary control loop is serially connected with successively the latching electromagnet in sensitive switch and isolation hands injured, sensitive switch is arranged on the back door of this high-voltage complete-set switch cabinet.
As preferably, described secondary control loop is provided with two fuses.
After adopting above structure, the utility model compared with prior art, has following advantage:
When the back door of high-voltage complete-set switch cabinet is opened, sensitive switch disconnects, latching electromagnet dead electricity, makes circuit breaker to close a floodgate, and isolation hands injured cannot be pulled out, when the back door of high-voltage complete-set switch cabinet is closed, sensitive switch closes, and latching electromagnet obtains electric, and circuit breaker can be closed a floodgate, after breaker closing, can by the pull-out of isolation hands injured; Electric blocking circuit of the present utility model employs sensitive switch and controls, dependable performance, easy to operate and cost is lower.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, the electric blocking circuit of the utility model high-voltage complete-set switch cabinet comprises the secondary control loop of high-voltage complete-set switch cabinet, described secondary control loop is serially connected with successively the latching electromagnet 2 in sensitive switch 1 and isolation hands injured, sensitive switch 1 is arranged on the back door of this high-voltage complete-set switch cabinet.
In fact latching electromagnet is exactly a mechanism blocking breaker switching-on operation, shrinks back and just can operate combined floodgate time charged, and not charged just ejection stops closing operation.
When the back door of high-voltage complete-set switch cabinet is opened, sensitive switch 1 disconnects, latching electromagnet 2 dead electricity, makes circuit breaker to close a floodgate, and isolation hands injured cannot be pulled out, when the back door of high-voltage complete-set switch cabinet is closed, sensitive switch 1 closes, and latching electromagnet 2 obtains electric, and circuit breaker can be closed a floodgate, after breaker closing, can by the pull-out of isolation hands injured.
Described secondary control loop is provided with two fuses, when electric current exceedes setting, fuse blows, open circuit, can protect circuit.
Below only apply preferably example with regard to the utility model and made explanation, but can not be interpreted as it is limitations on claims, structure of the present utility model can have other to change, and is not limited to said structure.In a word, all various changes done in the protection range of independent claims of the present utility model are all in protection range of the present utility model.
Claims (2)
