[0002] A substation is a place in a power system that transforms voltage and current, receives electrical energy, and distributes electrical energy. Substations in power plants are step-up substations, whose function is to step up the electrical energy generated by generators and feed it into the high-voltage power grid. The electrical equipment in a substation is divided into primary equipment and secondary equipment. Primary equipment refers to equipment that directly produces, transmits, distributes, and uses electrical energy, mainly including transformers, high-voltage circuit breakers, disconnect switches, busbars, surge arresters, capacitors, reactors, etc. Secondary equipment in a substation refers to equipment that measures, monitors, controls, and protects the operating conditions of primary equipment and systems. It mainly consists of relay protection devices, automatic devices, measurement and control devices, metering devices, automation systems, and DC equipment that provides power to secondary equipment. All maintenance work in a substation must be carried out in designated locations. To prevent workers from working outside their designated areas and accidentally climbing or touching live equipment, resulting in electric shock or equipment damage, safety fences should be set up around the work site.

[0003] However, the current installation and splicing methods of fences are cumbersome, and most are manufactured as a fixed unit, which causes great inconvenience for transportation and carrying. Therefore, this utility model provides an adjustable safety fence for substations to meet people's needs. Utility Model Content

[0027] The top two ends of the pressing plate 4 are symmetrically fixed with mounting sleeves 5. The mounting sleeves 5 are equipped with mounting studs 6. The mounting studs 6 and the mounting sleeves 5 are connected by threads. The top of the mounting studs 6 is fixedly connected with a compression rubber block 7. The top of the compression rubber block 7 is fixedly installed with a support rod 8.

[0028] A mounting groove 9 is provided in the middle of the supporting vertical rod 8. Safety railings 10 are installed at equal intervals between the middle of two supporting vertical rods 8. The two ends of the safety railings 10 are symmetrically fixed with partition blocks 11. The partition blocks 11 are movably engaged inside the mounting groove 9. Two adjacent partition blocks 11 fit together. The supporting vertical rod 8 is fixed above the trapezoidal strip plate 2 by the cooperation of the mounting sleeve 5 and the mounting stud 6. The splicing and fixing method is simple, which greatly facilitates the carrying and transportation of personnel and installation around the substation. The partition blocks 11 embedded in the mounting groove 9 play a role in positioning the safety railings 10. The safety railings 10 are horizontally distributed on the outside of the substation, which plays a role in surrounding protection of the substation. The partition blocks 11 support the adjacent safety railings 10, so that the adjacent safety railings 10 maintain a certain distance. There is no need for manual locking and adjustment. The number of safety railings 10 stacked can be adjusted according to the height of the substation and the installation protection requirements. The corresponding number can be selected and the installation method can be adjusted conveniently.

[0029] The bottom of the trapezoidal strip 2 is symmetrically provided with mounting screw holes 12 at both ends. Mounting rods 13 are installed at both ends of the bottom of the trapezoidal strip 2. A connecting stud 14 is fixedly connected to the top of the mounting rod 13.

[0030] The top of the trapezoidal strip 2 has symmetrically arranged grooves 15 at both ends. Pressure sensors 16 are fixedly installed inside the grooves 15. A controller 17 is fixedly installed at one end of the top of the substation mounting base 1. An alarm 18 is fixedly installed at the top of the substation mounting base 1, located to the side of the controller 17. A connecting stud 14 is movably embedded inside the mounting screw hole 12. The top of the pressure sensor 16 is higher than the top of the trapezoidal strip 2. The top of the pressure sensor 16 is in contact with the bottom of the pressing plate 4.

The upper positioning groove 19 and the lower positioning groove 20 are used to compare the angle and position of the rotating installation of the support vertical rod 8, which plays an auxiliary positioning role, so that the corresponding two support vertical rods 8 are kept horizontal, and the mounting grooves 9 are positioned corresponding to each other, so that the partition blocks 11 at both ends of the safety railing 10 can be installed and engaged smoothly.

[0032] The working principle and usage process of this utility model are as follows: First, the staff fixes the substation on the top of the substation mounting base 1, takes four trapezoidal strips 2 and places them on the outside of the substation mounting base 1. The four trapezoidal strips 2 correspond to the four sides of the substation mounting base 1, and the ends of the four trapezoidal strips 2 fit together. The mounting rod 13 is inserted into the mounting screw hole 12 by rotating the connecting stud 14, and the mounting rod 13 is inserted into the ground, which plays a role in fixing the trapezoidal strips 2.

[0033] Then, the staff took the support vertical rod 8, rotated and screwed the mounting stud 6 into the inside of the mounting sleeve 5, observed the position of the upper positioning groove 19, and ensured that the upper positioning groove 19 and the lower positioning groove 20 were aligned with each other when tightened. After the two support vertical rods 8 were fixedly installed, the two mounting grooves 9 corresponded to each other. The safety railing 10 was taken and installed from above. The partition block 11 was inserted into the inside of the mounting groove 9, and the upper and lower adjacent partition blocks 11 supported and adhered to each other, so that the safety railing 10 was evenly distributed between the support vertical rods 8, thereby blocking the outside of the substation. The number of safety railings 10 installed was adjusted according to the height of the substation and the installation protection requirements.

[0034] If a person or wild animal approaches the substation and steps on the pressing plate 4, the pressure sensor 16 will sense the pressure and transmit it to the controller 17, which will then control the alarm 18 to sound an alarm to drive the wild animal away, preventing it from damaging the substation or causing electric shock to unsuspecting people who accidentally touch it.
