2) The second auxiliary contact point in the control locking relay cuts off an electromagnetic braking circuit of the electric operation circuit.
Specifically, as described with reference to fig. 4, it is assumed that the ground lock is the lock 402 shown in fig. 4, which includes a communication module 4022, a card swiping sensing module 4024, an operation and display module 4026, and a lock module 4028, where the lock module 4028 is provided with a lock relay, which includes two pairs of contacts, one pair of contacts (a) is normally open, and the other pair of contacts (B) is normally closed. Here, the power supply 4062 and the electromagnetic brake circuit 4064 in the electric operation circuit 406 are controlled by the lock relay. In addition, the locker 402 here performs data interaction with the communication module 4042 in the controller 404 through the communication module 4022.
In this example, when the second operation authority for performing the ground lock operation is acquired, the normally open contact a is controlled to be closed and then normally open, and the normally closed contact B is controlled to be opened and then normally closed. The normally closed contact B returns to the normally closed state, the power supply of the grounding knife switch electric operation circuit is switched on, the normally open contact A returns to the normally open state, and the electromagnetic braking circuit in the electric operation circuit is cut off.
Through the embodiment that this application provided, realize the unblock control to earthing device through two pairs of contacts in the locking relay in the ground connection locking ware to reach the purpose of avoiding the maintainer to appear the safety risk.
The following examples may be combined to illustrate: suppose that the remote control system distributes 1 ID card (or a subway company ID work card) for each maintenance responsible person, inputs identity information into a background system, authorizes the persons meeting the requirements, and synchronizes the authorized data information to the controller of each grounding device. The following steps are specifically executed:
and S1, after the power failure of the contact network, the operation personnel executes the remote control closing operation of the grounding disconnecting link in a background system to realize the grounding of the contact network.
S2, before the maintainer enters the field for maintenance, the position of the disconnecting link of the grounding device (grounding disconnecting link) is checked, the disconnecting link position is confirmed to be in the closed position, an ID card is swiped on the grounding locker, the grounding locker sends the ID card to the grounding device controller, and the controller checks whether the card has the grounding locking authority.
1) If the ID card has no ground locking authority, the ground lock does not allow the locking operation and gives an audible prompt of unauthorized operation.
2) If the ID card has the ground locking authority, the buzzer of the ground locking device sends out an effective sound prompt for operation, and the ground locking operation is allowed to be executed.
And S3, the maintenance responsible person touches and presses the locking button, and meanwhile the grounding locker detects that the disconnecting link position of the grounding disconnecting link is closed, the grounding locker performs locking operation, and if the working responsible person performs locking operation on the device for the first time, the locking number is increased by 1. When the locking times is not 0, a locking indicator lamp is turned on, and a locking relay is started. A pair of contacts of the locking relay cut off the power supply of the electric operation loop of the grounding disconnecting link to lock the electric operation function of the grounding disconnecting link; the other auxiliary contact of the locking relay is connected with an electromagnetic braking loop of the electric mechanism to lock the manual operation function of the grounding disconnecting link; after the electric operation function and the manual operation function are locked, the grounding knife switch is locked in a grounding state. When a plurality of teams and groups work in parallel, each maintenance responsible person needs to execute locking operation respectively, and the grounding locking device displays the locked quantity in real time.
And S4, after the grounding state is locked, a maintainer can enter the field to execute a maintenance task, the remote control and the local manual operation of the grounding switch are reliably locked in the maintenance process, and the grounding switch is locked in the grounding state.
And S5, when the overhaul is finished and people are evacuated, the overhaul responsible person swipes a card on the grounding lock, the grounding device checks whether the overhaul responsible person has the authority, and when the condition is met, the touch and press of the 'lock reduction' button is prompted, the overhaul responsible person touches and presses the 'lock reduction' button, the grounding lock executes unlocking operation, and the locking number is reduced by 1. When a plurality of teams work in parallel, each maintenance responsible person needs to perform lock reduction operation before evacuation, and the sequence of locking of each team does not need to be considered. After all overhaul teams and groups execute the lock reduction operation, the locking number of the grounding locking devices is changed to zero, the grounding locking devices return, the locking indicator lamps are turned off, the locking relays are withdrawn, the grounding locking is released, and the electric operation function and the manual operation function of the grounding disconnecting link are recovered.
S6, when the overhead line system is overhauled, the maintainers sometimes can move along the single direction of the overhead line, and the overhead line system does not return to the original pull station when the overhaul is finished. For example, a service person may enter the station a after performing earthing switch locking and finally leave the station B, and all the traction stations passing in the middle perform earthing switch locking operation, so that the whole service line is locked in an earthing state. The invention supports the full-line unlocking function, and after the whole maintenance operation is finished, the maintenance responsible person performs the full-line unlocking operation at the finally evacuated traction station. The maintenance responsible person presses the 'unlock' button for a long time, the grounding locker transmits a full-line unlocking instruction to the whole network through the grounding device controller and the communication machine while executing the grounding locking unlocking operation of the device, and the grounding device which is executed by the maintenance responsible person and is locked is all unlocked.
