This utility model discloses a lightning protection power cabinet for new energy applications, belonging to the field of power equipment technology. It includes an outer casing and an inner casing, with the inner casing suspended inside the outer casing. An outer door is rotatably connected to the side of the outer casing, and an inner door is located on the side of the outer door. Several nylon support blocks connect the outer and inner casings, and between the outer and inner doors. The outer and inner doors respectively cover the openings of the outer and inner casings. A connecting frame is installed inside the inner casing near its top. In this design, the outer and inner casings are suspended and separated by nylon support blocks, forming a non-conductive air layer between them. This prevents external lightning current from being directly conducted to the electrical components inside the inner casing. A surge protector is installed on the connecting frame at the top of the inner casing, near the input terminal of the electrical components. It can quickly respond to lightning overvoltages, promptly discharge surge energy, and ultimately provide lightning protection for the electrical components.

The invention provides a voltage bleeder circuit suitable for positive and negative voltage output VCOM and a display driving chip, and the voltage bleeder circuit comprises a bleeder unit which is connected between the output end of the VCOM and a reference ground, and is used for discharging the positive voltage or the negative voltage of the output end of the VCOM to the reference ground in a bleeder mode; the control unit is connected to the control end of the discharge unit and is used for adaptively generating a grid control voltage according to the voltage polarity of the VCOM output end in a discharge mode so as to control the discharge unit to be conducted; wherein the discharge unit is in a turn-off state during normal work, and is turned on in response to grid control voltage in a discharge mode, so that self-adaptive discharge of positive voltage or negative voltage is realized. The voltage discharge circuit is low in cost, can rapidly and safely discharge the output voltage, protects the safety of devices, can be widely applied to various liquid crystal display driving chips, and has very high industrial practical value.

The invention belongs to the technical field of blasting, and particularly relates to a blasting oxygenation device and method adaptive to a plateau low-oxygen environment, the device aims at solving the problem that explosive blasting reaction is incomplete in the plateau hypoxia environment, the device comprises a charging bag placed in a blasting hole, an oxygenation device, a partition device and a sealing plug, the oxygenation device is provided with a shell and a liner bag, and the liner bag is provided with an opening. The inner container bag stores oxygen, the partition device is composed of an upper cover plate and an annular air bag, the oxygen increasing device and the partition device are arranged between every two vertically adjacent charging bags, the sealing plug is located at the top of the blast hole, and when the charging bags are detonated, generated shock waves can enable the inner container bag of the oxygen increasing device to be broken to release oxygen, and meanwhile the annular air bag of the partition device is pushed to expand to seal the hole wall. According to the device, oxygen release and sealing are triggered by means of explosion energy, oxygen is supplemented for a reaction area at the moment of explosion, oxygen is prevented from overflowing, and the plateau explosion effect can be improved.
