Example 1
The embodiment provides an actual application scenario of an emergency operation device applied to a multi-place rectification station in an electrolytic aluminum industry, which specifically comprises the following steps:
The emergency operation device is suitable for remote emergency operation control among more than 2 rectification houses, and aims to provide a remote emergency operation control device for the unattended rectification houses. As shown in fig. 3, an enterprise has a first rectifying station a and a second rectifying station B, and in order to improve labor productivity, the enterprise optimizes personnel configuration, decides to transfer all the operators on duty abolish at the station B, and all the upper computer remote control, remote measurement and remote signaling devices to the station a, so as to realize "one-to-two" management at the station a. As the position B is unattended, once the position B has sudden faults and the remote control, remote measurement and remote signaling equipment of the original position B which is migrated to the position A also has faults, the first button 10 and the second button 11 in the emergency operation device at the position A are required to be pressed down immediately, the high-voltage circuit breaker cut-off signal generated by the series emergency stop module 1 at the position A is triggered by the first button 10, and the on-load voltage regulating transformer downshift signal generated by the emergency downshift module 2 at the position A is triggered by the second button 11. The controller 4 at the A sends a high-voltage circuit breaker cut-off signal and an on-load voltage regulating transformer shift-down signal to the optical fiber transmission communication module 3 at the B through the optical fiber transmission communication module 3 at the A, the controller 4 at the B completely cuts off the high-voltage circuit breaker at the B according to the received high-voltage circuit breaker cut-off signal, and the shift position of the on-load voltage regulating transformer at the B is reduced to the lowest level according to the received on-load voltage regulating transformer shift-down signal. After the fault at B is completely relieved, the first button 10 and the second button 11 at a are rotated to complete the resetting of the emergency operation device. By arranging independent emergency operation devices at two parts of A, B, the remote emergency control among multiple rectification stations is realized, and the fault loss of equipment is reduced.

In addition, the aerial optical cable is adopted for independent optical fiber communication between the two side devices in a long distance, compared with a traditional hard wire connection mode, the mode is quick in signal transmission and high in safety, and meanwhile, in order to ensure the reliability of the emergency operation device, a double-network communication structure is adopted.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
The principles and embodiments of the present utility model have been described herein with reference to specific examples, the description of which is intended only to assist in understanding the methods of the present utility model and the core ideas thereof; also, it is within the scope of the present utility model to be modified by those of ordinary skill in the art in light of the present teachings.
