Description
Technical Field
[0001] The utility model relates to the technical field of wind power generation supporting equipment, in particular to a fully centralized monitoring and protection device for electrical equipment in a booster station. Background Art
[0002] A booster station refers to an overall system that converts the voltage of the passing charge. It is mainly used to boost the voltage in order to reduce the line current and thus the loss of electric energy. It is more common in wind power plants.
[0003] There are many electrical equipment in the substation, including various sensors, mutual inductors, measurement and control devices, etc. Many electrical equipment usually adopt a group of centralized monitoring equipment for centralized monitoring and protection to avoid safety hazards caused by electrical equipment failure. The current electrical equipment centralized monitoring and protection devices commonly used in substations are mostly similar in overall structure. They use a steel cabinet body with monitoring host, switches, batteries, distribution units and other components installed inside. The monitoring host connects to external sensors and monitors the operation of various electrical equipment. There are some functional deficiencies in actual use and there is room for improvement. For example, the current electrical equipment centralized monitoring and protection device is generally equipped with a group of smoke sensors inside, which can sense and warn when the internal circuit is on fire. However, the smoke sensor itself is fixed in position and will not be discovered until the smoke concentration inside the cabinet reaches a certain level. This means that the fire has already started to spread for some time. There is obvious lag and it does not have the function of quickly detecting smoke and fire.
[0004] Now, a new type of centralized monitoring and protection device for electrical equipment in a booster station is proposed to solve the above problems. Utility Model Content

[0014] Preferably, the micro electric cylinders are symmetrically distributed about the vertical center line of the cabinet, the fixed barrel and the pressure sensor are connected, and the steel extension rod can slide up and down along the inside of the fixed barrel.
[0015] Compared with the existing technology, the beneficial effects of the present invention are: the centralized monitoring and protection device for electrical equipment in the booster station not only realizes the function of quickly discovering smoke and fire, but also realizes the function of avoiding power outages and shutdowns, and also realizes the function of stable support and anti-swaying;

The four sets of steel extension rods touch the ground at the same time. The pressure sensor senses the reaction force fed back upward by the steel extension rods. When the pressure of the four sets of steel extension rods reaches the preset value, the micro electric cylinder stops extending. At this time, the four corners of the equipment are evenly stressed and in a balanced state, achieving the function of stable support and anti-sway. BRIEF DESCRIPTION OF THE DRAWINGS

An audible and visual alarm 13 is fixedly connected to the right side of the top of the cabinet 1.
[0028] The top of the ventilation duct 9 is flush with the top of the cabinet 1. The negative pressure fan 8 and the interior of the ventilation duct 9 are connected. The vertical center lines of the ventilation duct 9, the cross fixing frame 10, and the gas sensor 11 coincide with each other. The gas sensor 11 and the sound and light alarm 13 are electrically connected. The air inlet slots 12 run through the inside and outside of the cabinet 1. The air inlet slots 12 are arranged at equal intervals, which can quickly sense and warn in the early stage of a fire.
[0029] Specifically, if Figure 1 、 Figure 3 and Figure 4 As shown, the negative pressure fan 8 is in the normally open state, exhausting the air inside the cabinet 1, and the external air enters the cabinet 1 along the air inlet slot 12, reducing the heat accumulation inside the cabinet 1. When a circuit fire occurs inside the cabinet 1 and the smoke passes through the ventilation duct 9, the gas sensor 11 at the bottom of the cross fixing frame 10 can quickly capture the smoke, and the sound and light alarm 13 will sound an alarm simultaneously, and the negative pressure fan 8 will be turned off at the same time, so that timely warning can be given at the early stage of the fire to avoid the spread of the fire.
[0030] Embodiment 2: A control circuit board 14 is fixedly connected to the left side of the interior of the housing 3, a power-off sensor 15 is installed at the rear end of the right side of the control circuit board 14, a power input interface 16 is provided at the bottom of the rear end of the housing 3, a power output interface 17 is provided at the top of the rear end of the housing 3, a battery docking interface 18 is provided at the top right side of the control circuit board 14, the battery pack 2 and the battery docking interface 18 are electrically connected, the power distribution unit 7 and the power output interface 17 are electrically connected to the sound and light alarm 13, and the power-off sensor 15 are electrically connected.

The relevant wiring of the entire booster station electrical equipment is uniformly connected to the monitoring host 5 for centralized monitoring. During normal operation, the protective door 19 is closed and the negative pressure fan 8 is normally open, exhausting the air inside the cabinet 1. External air enters the cabinet 1 through the air inlet slot 12, reducing heat accumulation within the cabinet 1. When a circuit fire occurs inside the cabinet 1 and smoke passes through the ventilation duct 9, the gas sensor 11 at the bottom of the cross-mount 10 can quickly detect the smoke, and the sound and light alarm 13 will simultaneously sound an alarm. The negative pressure fan 8 will also be turned off, providing a timely warning at the early stage of the fire and preventing the spread of the fire. External power is connected to the power input interface 16 to power the equipment, while the battery pack 2 is powered through the battery docking interface 18. When the power failure sensor 15 on the control circuit board 14 senses a power interruption at the power input interface 16, the battery pack 2 begins to power the equipment, and the sound and light alarm 13 will simultaneously sound an alarm, prompting personnel to check. After the equipment is installed, the micro-electric cylinder 23 extends downward, pushing the steel extension rod 26 downward along the fixed barrel 24. The four groups of steel extension rods 26 touch the ground at the same time. The pressure sensor 25 senses the reaction force fed back upward by the steel extension rods 26. When the pressure of the four groups of steel extension rods 26 reaches the preset value, the micro-electric cylinder 23 stops extending. At this time, the four corners of the equipment are evenly stressed and in a balanced state.
