Description

Technical Field

[0001] The invention relates to the technical field of transformer substations, in particular to a prefabricated electric power substation with fire monitoring. Background Art

[0002] Prefabricated cabin substation is also an outdoor substation. Its main transformer and the main electrical equipment such as circuit breakers, disconnectors, high-voltage transformers on the primary side of the main transformer are installed outdoors, just like ordinary or conventional outdoor substations. The difference from ordinary or conventional outdoor substations is the installation and manufacture of the main equipment on the secondary side of the main transformer, as well as instruments, relay protection devices, control equipment, DC power supplies, and communication equipment. In addition, only the main transformer can be installed outdoors, while the main electrical equipment such as circuit breakers, disconnectors, high-voltage transformers on the primary side of the main transformer adopt GIS complete sets of power distribution devices and are installed in the GIS cabin.

[0003] The existing substations have the problem that when a fire occurs, the fire inside the substation cannot be discovered and handled in time, which can easily cause damage to the substation and affect the power supply quality. At the same time, the integrated design of the substation is inconvenient for personnel to expand, transform and maintain it later. At the same time, the substation has a fixed height, and when rainwater accumulates, it is easy to penetrate into the inner cavity of the substation and cause damage to the power station equipment.

[0042] Furthermore, the monitoring installation structure 10 includes a mounting frame 101 fixedly connected to the upper rear end surface of the inner cavity of the protective plate 22, a power rail 102 is provided on the front end surface of the mounting frame 101, a connecting block 103 is slidably connected to the inner cavity of the power rail 102, the connecting block 103 is electrically connected to the mounting frame 101 through the power rail 102, a signal processing module 104 is fixedly connected to the upper rear end surface of the protective plate 22, the mounting frame 101 is electrically connected to the signal processing module 104, and dry powder is sprayed through the spray pipe 93 in case of fire, so as to extinguish the fire. Through the monitoring installation structure 10 on the protective structure 2, it is convenient for personnel to install and place the fire monitoring equipment during use, and it is also convenient to load, unload and replace the monitoring equipment.

[0043] Working principle:

[0044] During operation, the base plate 1 is placed at a suitable position on the ground. At this time, the personnel splice the protective plate 22 and the rainproof structure 3 through the installation block 21. At this time, the protective door 23 is pulled to rotate the protective door 23 toward each other, thereby opening the protective plate 22. At this time, the personnel place the electronic equipment in the inner cavity of the protective plate 22.

[0045] When a fire occurs in the inner cavity of the protective structure 2, the detection sensor on the connection block 103 is activated. At this time, the signal is transmitted to the signal processing module 104 through the power rail 102 and the mounting frame 101, thereby generating an alarm. At the same time, the pressure pump in the inner cavity of the dry powder storage box 91 is activated, so that the dry powder in the inner cavity of the dry powder storage box 91 is sprayed into the device through the spraying pipe 93, thereby extinguishing the fire in the inner cavity of the device.

[0046] When rainwater accumulates, the driving structure 5 is started, so that the output end of the driving motor 53 rotates, so the driving gear 52 rotates, and then the toothed belt 51 rotates, so the transmission gear 43 rotates, so that the worm 42 rotates, and since the worm 42 and the worm wheel 41 are meshed with each other, the worm wheel 41 rotates, so that the threaded rod 61 rotates, and since the threaded sleeve 62 is fixedly connected to the lifting plate 63, the height of the bottom plate 1 rises, thereby preventing water from entering the inner cavity of the device and causing leakage damage to the equipment.

[0047] When the device is placed on a cut surface, the electric telescopic rod 73 on the lower side extends, so the cross shaft 82 and the lower rotating frame 83 rotate, and at the same time the electric telescopic rod 73 on the lower side contracts, and the cross shaft 82 and the lower rotating frame 83 rotate in the opposite direction, so that the device can still be placed horizontally on an inclined surface.
