The structure can cover the whole control display screen area of the charger inverter equipment, and particularly effectively avoids the risk of accidental touch of people for a startup and shutdown button of the charger inverter equipment; when the charger inverter equipment needs to be checked for parameters, the square window reserved in the protective cover can be convenient for operators to operate without taking down the protective cover.
Description
Technical Field
The invention belongs to the technical field of nuclear power plant equipment maintenance, and particularly relates to a protection cover for preventing a nuclear island charger inverter of a nuclear power plant from being touched by people by mistake.
Background
The nuclear power plant nuclear island charger inverter is used as an upstream power supply device of important safety loads of a nuclear power plant, and the safe and stable operation of the nuclear power plant nuclear island charger inverter is directly related to the normal operation of equipment such as nuclear power plant unit reactor monitoring, important safety facilities, a shutdown protection logic cabinet and the like. If the equipment is abnormally powered off and shut down, the unit is shut down and shutdown is probably caused, and the risk is extremely high.
Considering that the operation panel of the charger inverter belongs to physical key control and is protected against false touch at present, during the operation period of a certain nuclear power plant in China, the event that the operation panel of the charger and the operation panel of the inverter equipment are touched by human mistake for many times, which causes the power loss of a downstream load, causes the operation state change of the charger inverter and even the shutdown and shutdown of the charger inverter, and has great influence on the operation performance of the nuclear power plant.
Disclosure of Invention
The invention aims to provide a protection cover for preventing a nuclear island charger inverter in a nuclear power plant from being touched by mistake due to human factors, so that the occurrence of the accident of touching the charger inverter by mistake can be avoided, and the risk of human factor errors is reduced.
The technical scheme of the invention is as follows: a nuclear power plant nuclear island charger inverter anti-human factor mistaken touch protective cover comprises a protective cover body and a magnet block, wherein the protective cover body is of a transparent rectangular cover-shaped structure and is matched with a nuclear power plant nuclear island charger inverter control display screen in size; the protection cover body is reliably attracted to a cabinet door of the charger inverter equipment through the magnet blocks, so that the protection cover body can completely cover the control display screen of the charger inverter.
The protection cover body is provided with an operation window, the size of the operation window is matched with that of a digital key area of the charger inverter, and when the protection cover body is buckled on a control display screen of the charger inverter, the operation window is overlapped with the digital key area of the charger inverter.
The safety cover body open all around have a plurality of magnet mounting groove, the magnet piece match the setting in the magnet mounting groove.
The safety cover body open all around have 6 magnet mounting grooves, two long limits respectively open about the safety cover body have two magnet mounting grooves, respectively open at two minor faces has a magnet mounting groove, all install the magnet piece in every magnet mounting groove.
Magnet piece cladding have the protection cover body after the shell with the material, fixed the setting in the magnet mounting groove.
The length and width of the magnet block are 20mm multiplied by 5mm, and the thickness is 2 mm.
The safety cover body adopt transparent aviation organic glass, whole thickness is 5 mm.
The invention has the following remarkable effects: the protection cover for preventing the nuclear island charger inverter in the nuclear power plant from being touched by mistake due to human factors can cover the control display screen area of the charger inverter device integrally. Particularly for the startup and shutdown button of the charger inverter equipment, if the startup and shutdown button needs to be operated, the protective cover needs to be manually taken down, otherwise, the button cannot be touched manually, and the risk of mistaken touch of a person is effectively avoided; when the charger inverter equipment needs to be checked for parameters (without switching on and off), the square window reserved in the protective cover can be convenient for an operator to operate without taking down the protective cover. Meanwhile, the protective cover is made of transparent materials, so that the normal observation of the running state of the charger inverter equipment by an operator is not influenced.
Drawings
Fig. 1 is a schematic diagram of a protection cover of a nuclear island charger inverter of a nuclear power plant for preventing accidental human collision;
in the figure: 1. a protective cover body; 2. a magnet block; 3. a magnet mounting groove; 4. and operating the window.
Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1, the protection cover for preventing the nuclear island charger inverter of the nuclear power plant from being touched by mistake by people comprises a protection cover body 1 and a magnet block 2, wherein the protection cover body 1 is integrally of a rectangular cover-shaped structure and is matched with the size of a control display screen of the nuclear island charger inverter of the nuclear power plant; the protective cover body 1 is made of transparent aviation organic glass, and the whole thickness is 5 mm; a plurality of magnet mounting grooves 3 are formed in the periphery of the protective cover body 1, and a magnet block 2 is adhered to each magnet mounting groove 3; for example, 6 magnet mounting grooves 3 are formed around the protection cover body 1, two magnet mounting grooves 3 are formed in the upper and lower long edges of the protection cover body 1, one magnet mounting groove 3 is formed in each of the two short edges, a magnet block 2 is mounted in each magnet mounting groove 3, each magnet block 2 is 20mm multiplied by 5mm, the thickness of each magnet block is 2mm, the protection cover body 1 is wrapped around each magnet block 2, the magnet block 2 is prevented from directly contacting with a charger inverter cabinet door, and the magnet block is left on the cabinet door due to overlarge magnetic force; an operation window 4 in a rectangular opening shape is arranged on the protective cover body 1, wherein the size of the operation window 4 is matched with the size of a numeric keypad of a charger inverter control display screen.
