The temperature acquisition device 70 is arranged in the wind power box transformer. The backplane bus 10 is used for electrically connecting the human-computer interaction panel 20, the power supply board insert 30, the incoming board insert 40, the central processing unit board insert 50 and the alternating current acquisition board insert 60, so that the human-computer interaction panel 20, the power supply board insert 30, the incoming board insert 40, the central processing unit board insert 50 and the alternating current acquisition board insert 60 can interact information.

[0027] The human-computer interaction panel 20 includes a display device 21 and an input device 22, and the display device 21 and the input device 22 are electrically connected to the backplane bus 10 respectively. The display device 21 is used for data display, and the input device 22 is used for inputting data. The display device 21 and the input device 22 can be integrated into a device with both display function and input function, for example, a touch screen. The display device 21 and the input device 22 can also be separated, and the display device 21 can be a cathode ray tube display, a plasma display, a liquid crystal display, a light emitting diode display, a touch screen and the like, and the input device 22 can be a keyboard, a mouse, a mechanical button and the like.

[0028] The power supply board insert 30 includes a power supply component 31, a plurality of outgoing relays 32 and an oil temperature acquisition component 33 for receiving the oil temperature signal of the wind power box transformer. The plurality of outgoing relays 32 and the oil temperature acquisition component 33 are electrically connected to the power supply component 31 respectively, and the power supply component 31 is electrically connected to the backplane bus 10.

[0029] The power supply component 31 converts the commercial power (alternating current 220V) into direct current 5V, which is used for providing working power for the wind power box transformer monitoring and control device 1. The plurality of outgoing relays 32 can be used for remote circuit breaker control and alarm. The number of the outgoing relays 32 is set according to actual needs, and in this embodiment, the outgoing relays 32 have 6 groups. The oil temperature acquisition component 33 can receive the oil temperature signal of the wind power box transformer, and the oil temperature signal is generally a thermal resistance signal or a 4-20ma signal.

[0030] The incoming board insert 40 is an optional insert, and the number of the incoming board insert 40 is optional. In this embodiment, the incoming board insert 40 includes 32 terminals, and provides 31 incoming signals for remote transmission, including remote on-site signals, isolating switch positions and the like.

[0031] The alternating current acquisition board insert 60 is internally provided with a current transformer 61 and a voltage transformer 62, which can provide acquisition of analog quantities and transmit the analog quantities to the central processing unit board insert 50 through the backplane bus 10 for logical operation. The analog quantities include 6 voltage signals, 6 current signals and 2 zero sequence current signals.

[0032] As Figure 2 shown, the central processor board card 50 includes a wireless signal receiving component 52, a processor 51, a network component 53 and a fiber ring network component 54.

[0033] The wireless signal receiving component 52 and the processor 51 are electrically connected, and the processor 51 is electrically connected with the backplane bus 10. The wireless signal receiving component 52 is used to receive the temperature data wirelessly transmitted by the temperature acquisition device 70, and transmit the temperature data to the processor 51. The processor 51 acquires the temperature data, and judges whether the temperature data exceeds a first preset temperature value. If the temperature data is within the first preset temperature value range, the processor 51 does not process, and only transmits the temperature data to the background. If the temperature data exceeds the first preset temperature value, the processor 51 judges the position of the circuit breaker. When the circuit breaker is in the closed position, the processor 51 drives the opening relay 32 of the power supply board card 30 to act through the backplane bus 10, disconnects the circuit breaker, and then sends an over-temperature trip signal for remote transmission and display. When the circuit breaker is in the open position, the processor 51 only sends an over-temperature trip signal for remote transmission and display.

[0034] The first preset temperature value can be flexibly set according to the actual situation of each to-be-measured point, such as the position of each to-be-measured point, the temperature value when normally working, and the temperature value when not normally working.

[0035] The central processor board card 50 expands multiple groups of RS485 interfaces 531 and multiple groups of gigabit Ethernet interfaces 532 through the built-in network component 53. Each wind power box transformer measurement and control device 1 can be connected through the RS485 interface 531, then connected to the communication management machine, and then connected to the background through the communication management machine. The gigabit Ethernet interface 532 is mainly used to provide access of external data (smart devices such as high-definition cameras and IP phones) and for debugging of the wind power box transformer itself. When the wind power box transformer is debugged, it will be connected to the gigabit Ethernet interface 532 of the wind power box transformer measurement and control device 1 through a network cable to transmit configuration, and is not needed after debugging. Using gigabit Ethernet can provide higher bandwidth to meet the increasing demand for network data flow speed. Accessing smart devices through Ethernet will not affect the communication of other devices, greatly reducing the wiring amount of communication devices of other devices in the power station, and having the advantages of high efficiency, high speed and high performance.
