Detailed Description
The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It is to be understood that the description herein is merely for purposes of illustration and explanation and is not intended to limit the embodiments of the present invention.
In the embodiments of the present invention, unless otherwise specified, the use of directional terms such as "upper, lower, top, and bottom" is generally used with respect to the orientation shown in the drawings or the positional relationship between the components in the vertical, or gravitational direction.
In addition, if there is a description in the embodiments of the present invention referring to "first", "second", etc., the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments can be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or can not be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.
Fig. 1 is a block diagram illustrating a state monitoring system of an all-fiber current transformer according to an embodiment of the present invention. In fig. 1, the monitoring system may include a plurality of photocurrent transformers 01, a switch 02, and a main control room 03.
The photocurrent transformer 01 may be a plurality of and respectively disposed on each electronic unit in the relay chamber, and the electronic unit may be, for example, each relay node, an on-off switch, and the like in the relay chamber. When the electronic unit is connected, the photocurrent transformer 01 may be disposed near the electronic unit circuit or directly mounted on the circuit.
The switch 02 may be connected to each photocurrent transformer 01 in the corresponding relay room. Specifically, since the photocurrent transformer 01 transmits information through an optical signal, the switch may be connected to the photocurrent transformer 01 through a communication cable. The main control room 03 is connected with each switch 02, so that the current intensity measured by each photocurrent transformer 01 is obtained through the switches 02, and the technical effect of monitoring whether each electronic unit in each relay room works normally or not in real time is finally achieved.
In operation of the monitoring system shown in fig. 1, a worker located in the main control room 03 monitors the current intensity of each electronic unit in real time to determine whether it is malfunctioning. Generally, when any electronic unit fails, a worker needs to go to a relay room where the corresponding electronic unit is located to check and repair the electronic unit. Since the main control room 03 and the relay room are generally far apart, it is unlikely that a worker will return to the main control room 03 to determine whether the current electronic unit has returned to normal during the repair of the relay room. Therefore, in one embodiment of the present invention, as shown in fig. 2, the monitoring system may include a first display screen 04. This first display screen 04 can set up in the relay room to be connected with the switch that this relay room corresponds, be used for the current relay indoor each electronic unit's of real-time display current intensity, thereby make the staff can look over current relay indoor each electronic unit's the behavior in real time through this first display screen 04 at the in-process of overhauing or patrolling.
Because the relay rooms corresponding to the switches 02 need to be monitored simultaneously in the same main control room 03, a large number of communication optical cables are often connected to the interface end of the main control room 03. In order to facilitate the unified centralized placement of these optical cable interfaces, make in the master control room 03 can keep clean and tidy, from the reasonable arrangement of the equipment of being convenient for the utility model discloses an embodiment, as shown in fig. 3, this monitored control system can also include the public secondary equipment room 05 of station, and the public secondary equipment room 05 of this station can be connected between switch 02 and master control room 03 for the same cable of concentrated access each switch 02.
In addition, in the actual working process of the main control room 03, not only each relay room in the converter station needs to be monitored in real time, but also external environmental conditions need to be determined in real time, so that whether each electronic unit in the relay room is changed due to the environmental conditions is judged. Various sensors are necessary to determine the external environmental conditions. Therefore, in one embodiment of the present invention, as shown in fig. 4, the monitoring system may include a communication room 06. The communication machine room 06 can be connected between the switch 02 and the main control room 03 and includes a temperature sensor and the like. The temperature sensor and the like may be used to acquire conditions such as external temperature, so that the main control room 03 may acquire external environmental conditions in real time.
Further, similar to the first display screen 04 described above, in order to further facilitate the working personnel to be able to address the real-time status of the electronic unit when servicing the equipment. The monitoring system may also include an optical CT merge unit screen 07. As shown in fig. 5, the optical CT merging unit 07 may be connected between the switch 02 and the photocurrent sensor 01, and disposed near the corresponding electronic unit for displaying the current intensity in real time.
Through the technical scheme, the utility model provides an all-fiber formula current transformer state monitoring system is through setting up photocurrent transformer on the electronic unit of relay room to transmit the current strength who measures to the master control room through optic fibre, realized the long-range and unified control to the relay room.
