4th position of contact and the auxiliary switch normally opened contact second position of breaker connect.
Change-over switch 3 is existing common change-over switch, in actual work, when operation handle 4 of the invention gets to centre
When zero setting gear positions, the present invention is to cut out state, corresponding circuit connection Fig. 3 are as follows: each operation of the device section of breaker
Circuit is mutually disconnected with each test loop of change-over switch 3, each circuit of mechanism section of breaker, plays one kind in case of a fault
The effect electrically separated.
When operation handle 4 of the invention gets to operation range position, the present invention is normal condition, and corresponding circuit connects
Line as shown in figure 4, protection device for circuit breaker section operation circuit by change-over switch 3 each Loop Contacts first position with
The corresponding circuit of mechanism section of breaker is connected directly, and plays the role of a kind of transition connection under normal circumstances.
When operation handle 4 of the invention gets to test gear positions, the present invention is incision state, and corresponding circuit connects
As figure 5 illustrates, at this moment, 3 closing circuit of change-over switch tests contact and the access open circuit of 3 sub-gate circuit of change-over switch test contact to line chart
The control loop of device is equivalent to and has accessed a branch in parallel with the mechanism section of breaker on breaker control circuit, in event
Play the role of a kind of loop signal in the case of barrier from ring.
Operation handle 4 should should be beaten in operating position in normal operating condition, otherwise will cause control loop by the present invention
It is obstructed.For the present invention in test mode, control loop access is a TCH test channel, cannot be grasped at this time to breaker
Make, otherwise will cause control power supply and be spaced apart tripping, after being completed, operation handle 4 should should be beaten in zero setting gear, be prevented because disconnected
Road device control loop failure and cause other operating troubles.
Structure of the invention is reasonable and compact, easy to use, under breaker control circuit fault condition, is converted using one
One test loop is cut into the control loop of breaker by switch 3, to verify from the present invention to the control of breaker mechanism section
Circuit processed whether connection, so that it is determined that failure occur in which section in circuit.The present invention makes breaker control circuit failure
The arrangement and distribution for handling work have more reasonability, the professional structure of troubleshooting staffs has more specific aim, to reach contracting
Response time of short breakdown repair order, reduce the expenditure set out person-time, save troubleshooting work of troubleshooting operation at
This, plays the basic goal of upgrading synergistic effect conscientiously.
Above-mentioned breaker control circuit can be made further optimization and/or improvements from loop device according to actual needs:
As shown in attached drawing 1,2, the rotation angle range of operation handle 4 is 0 ° to 90 °.
The rotation of operation handle 4 to left side obliquely 45 ° when, that is, be designated as getting to operation range, operation handle 4 is rotated into
Between forward position when, that is, be designated as getting to zero setting gear, the rotation of operation handle 4 to right side obliquely 45 ° when, that is, be designated as beating
To test gear.The position for testing gear and operation range can also be interchangeable according to actual needs, it is user-friendly.
The above technical characteristic constitutes highly preferred embodiment of the present invention, with stronger adaptability and best implementation effect
Fruit can increase and decrease non-essential technical characteristic, according to actual needs to meet the needs of different situations.
The working principle of the invention is: breaker control circuit is manually divided into two parts at breaker terminals case,
A part is from terminal box to protective device (referred to as device section), and a part is from terminal box to mechanism section (referred to as mechanism section).
When protective device issues breaker control circuit wire break alarm signal, live operation maintenance personnel only need to be by manipulator of the invention
Handle 4 gets to test gear by zero setting gear, then goes the alarm signal in involution protective device again, if energy involution, can sentence
Disconnected trouble location is in mechanism section, if being unable to involution, it can be determined that trouble location is in protective device section.In this way, practical peace
When arranging work, overhaul of the equipments department first carries out with live operation maintenance personnel before arranging work when being connected to breakdown repair order
Necessary work can targetedly arrange skilled addressee to carry out troubleshooting after linking up.
