[0058] Project scope

[0059] This project is a retrofit project on the existing 220kV Jiangbei transformer primary equipment. The retrofit scope includes the phase-to-phase transmission rod of the 220kV GIS part, and the associated control cabinet of the knife switch equipment.

[0060] The project construction scope includes the installation and debugging of double-confirmation magnetic induction sensors, wiring from the magnetic induction sensors to the receiving device, connection of accessories and terminal blocks, and installation and debugging of the receiving device.

[0061] Installation scheme of knife switch magnetic induction sensor

[0062] 220kV GIS equipment is the product of Xi'an Xidian High Voltage Switch Co., Ltd. The equipment of this type of this manufacturer has been adapted and matched, and the double confirmation sensor of magnetic induction principle can be used to collect the on-off signal of the knife switch.

[0063] After investigation and size measurement, the disconnector of 220kV GIS is a mechanism with three-phase structure, and the transmission structure is three-phase mechanical linkage. There are three places for magnetic induction installation:

[0064] The on-off indicating cover (fish eye). However, the installation at this position involves opening the mechanism box for measurement and installation during power failure, which is not convenient for installation and maintenance.

[0065] The end position of the rotating shaft. After investigation, the installation at this position requires punching and fixing, but the surface hardness of the GIS equipment is high, and it is difficult to punch. Moreover, the punching vibration may cause unknown risks such as power failure;

[0066] The rotating shaft connecting rod of the interphase transmission rod. This position can be fixed and installed with magnetic induction by using the original screw hole on the mechanism, but three-phase installation is not possible (only one phase can be installed).

[0067] Considering the installation conditions, construction and maintenance convenience, the third position is the most suitable for on-site installation. The sensor is recommended to be installed at the connecting rod of the transmission rod.

[0068] Installation specifications:

[0069] The knife switch sensor is installed at the transmission rod with matching accessories;

[0070] The knife switch sensor cable is sealed with a metal-plastic soft tube, and is routed through the cable tube and cable trench to the terminal cabinet.

[0071] Installation of receiving device

[0072] The receiving device is installed in each interval intelligent terminal cabinet. If the original intelligent terminal spare contact in the cabinet is not enough, a separate measurement and control device needs to be configured for each knife switch state signal input.

[0073] The intelligent terminal cabinet needs to install knife switch receiving device, power supply and air switch electronic devices, which are installed in the control cabinet using guide rails. In addition, the cabinet has 220V power supply for the knife switch receiving device.

[0074] The knife switch receiving device needs to have 3 ports + 1 COM port,

[0075] Cable laying

[0076] The length of the cable from the receiving device to the sensor should not exceed 40 meters, otherwise the communication cannot be guaranteed.

[0077] Cabling needs cabling slot, should be required by the station and may need to increase corrugated pipe and galvanized pipe in part of the cabling segment protection.

[0078] Cabling needs to use metal strap to fix stable.

[0079] Measurement and control access and signal sending

[0080] According to the design institute wiring diagram and scheme access measurement and control;

[0081] Go through the existing channel, no need to change;

[0082] Remote device through IEC 61850\104 protocol to send the device state to the dispatching control system, as the state of the control operation (programmed operation) double confirmation basis.
