Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In view of the problem of high monitoring cost of switch stations in the prior art, an embodiment of the utility model provides an unattended simple switch station for gathering new energy. FIG1 is one of the connection schematic diagrams of the unattended simple switch station for gathering new energy provided by an embodiment of the utility model. As shown in FIG1 , the switch station includes:

At least two fiber switches 120, wherein the at least two fiber switches 120 are connected to the booster station monitoring system 110;

A protection, measurement and control device 130, wherein the protection, measurement and control device 130 is connected to a corresponding fiber optic switch 120 among the at least two fiber optic switches 120;

35KV power distribution device 150, the 35KV power distribution device 150 is connected to the protection and measurement and control device 130;

A power supply device 160, wherein the power supply device 160 is connected to the protection and measurement control device 130;

A complete environmental control system 140 is connected to a corresponding fiber optic switch 120 among the at least two fiber optic switches 120 .

Specifically, when constructing a switch station, at least two fiber optic switches 120, a protection and measurement and control device 130, a 35KV distribution device 150, a power supply device 160 and a complete environmental control system 140 are deployed in the switch station, wherein the 35KV distribution device 150 is connected to the bus and serves as a device for collecting electric energy and distributing electric energy to each device in each switch station. The power supply device 160 is used to supply power to each load in the switch station to ensure the normal operation of the switch station. The 35KV distribution device 150 and the power supply device 160 can be used to collect their corresponding power monitoring data to determine whether each device has a fault. After collecting the power monitoring data, the power monitoring data can be transmitted to the protection and measurement and control device 130. After obtaining the power monitoring data, the protection and measurement and control device 130 can transmit the power monitoring data to the booster station monitoring system 110 through the connected optical fiber switch 120. After the booster station monitoring system 110 performs an abnormality detection based on the power monitoring data, if an abnormality occurs, a corresponding control instruction can be generated, and the control instruction is first transmitted to the protection and measurement and control device 130 through the optical fiber switch 120, and then the protection and measurement and control device 130 transmits or executes the control instruction. Through the data transmission between the protection and measurement and control device 130 and the booster station monitoring station, the transmission cost of the distribution data is reduced, and the line corridor occupied by the use of multiple collector lines is avoided. For example, if a local collector line in a 35KV distribution device 150 is abnormal, the protection measurement and control device 130 can execute the control instruction to disconnect the local collector line, thereby preventing the local fault from causing a power outage in the entire 35KV distribution device 150 and causing a larger fan to stop, that is, preventing the local fault from causing a larger power outage range and causing a larger power loss.

In addition, the complete environmental control system 140 can collect environmental monitoring data within the switch station and send the environmental monitoring data to the substation monitoring system 110 through the connected fiber optic switch 120 for remote monitoring. If an abnormality occurs, a control instruction can be sent through the fiber optic switch 120 to control the corresponding equipment to start or shut down, thereby reducing the degree of abnormality in the switch station and achieving safe operation of the switch station.

Optionally, the protection and measurement control device 130 is configured with three-stage overcurrent protection and two-stage zero-sequence protection.

Furthermore, it also includes an equipment cabin 100, wherein the at least two fiber optic switches 120, the protection and measurement and control device 130, the 35KV power distribution device 150, the power supply device 160, and the complete environmental control system 140 are all arranged in the equipment cabin 100, and the protection and measurement and control device 130 is arranged above the 35KV power distribution device 150.

The 35KV distribution device 150 adopts open-door operation and maintenance in the equipment cabin 100, which is convenient to operate and reduces the implementation cost and maintenance cost.

Furthermore, the equipment cabin 100 adopts a box-type cabin, and a communication optical cable interface and a high-voltage cable interface are provided on the outside of the equipment cabin 100.

It occupies a small area, and the space volume of the equipment cabin 100 is small, which can meet the overall road transportation conditions and reduce transportation costs. In addition, the lifting conditions are met when the equipment cabin 100 is installed, that is, the entire switch station can be lifted by a crane to the installation address and then installed, which reduces the installation cost. In addition, a communication optical cable interface and a high-voltage cable interface are set on the outside of the entire equipment cabin 100. The communication optical cable interface is respectively connected to at least one optical fiber switch 120 and a booster station monitoring system 110, and the high-voltage cable interface is respectively connected to the power grid and the 35KV distribution device 150. The entire switch station is debugged before leaving the factory, and no on-site debugging is required after the switch station is installed, which shortens the installation period of the switch equipment, thereby improving the installation efficiency and reducing the debugging cost.
