    [0001] The present invention relates to the field of control of the reactor, particularly the electromagnetic coil for the drive mechanism of the pressure control rods of the pressurized water reactor. (REP).
    [0002] Since the reactor is the core part of the nuclear power plant, the upper flange mounted control rod drive mechanism of the reactor vessel will be rising, falling or maintained in the position of the control rods in the core, and usable to control the rate of fission of the reactor in order to start and stop the reactor, and to regulate the power of the reactor. In crash mode, the control rod drive mechanism will descend rapidly to insert the control rods (dropping the rods quickly) and shut down the reactor in the short term to ensure safety. The drive mechanism of the control rods is inseparable to implement these functions. Due to the specific service environments and essential functions, the electromagnetic coil must be safe and reliable by characterizing by high service temperature resistance, excellent insulation properties, radiation resistance, etc. For a long time, the resistance to high temperature can only be reached with the level of about 250 ° C for the electromagnetic coil components of the control rod drive mechanism in the nuclear power plant, while the fluid temperature reactor cooling is over 300 ° C. Therefore, in practice, only methods such as air cooling, etc. will be applicable to cool the electromagnetic coil components of the control rod drive mechanism thereby causing the complexity of the structures of the upper flange of the nuclear reactor. It is an object of the present invention to provide an electromagnetic coil insulating structure, an outer casing of the electromagnetic coil and an internal frame to solve the problem of insufficient resistance to high temperature electromagnetic coil components of the drive mechanism of the electromagnetic coil. control in the nuclear power plant. The outer casing in this insulating structure is used to increase the resistance of the entire coil insulating structure in order to not only improve the resistance to moisture and vibration resistance for the electromagnetic coil, but also to effectively maintain the insulation. long-term integrity of the electromagnetic coil, preventing the destruction of the insulating structure resulting from the impregnation of high temperature resistant varnish and the progressive dissipation of quartz sands, and obviously improving the high temperature resistance property and the lifetime of the electromagnetic coil. The object of the present invention is achievable by the following technical solution: The insulating structure of the electromagnetic coil, comprises the outer casing, the internal frame, the winding of the coil and the sealed insulating layer; and the winding of the coil being surrounded in the internal framework; an end of the outer casing being bonded to another end of the inner frame, while the other end of the outer casing is not bonded to the internal frame; the sealed insulating layer being implanted between the winding of the coil and the outer casing, characterized in that: the outer casing being metallic; a game being open on the outer casing to pass through the upper part and the lower part of the outer casing; said game is connected and fixed by the insulation and clamping band; the internal framework being metallic; a play being open on the internal framework to cross the upper part and the lower part of the internal frame; it also comprising an isolation bar to be incorporated in the game. Additionally, said insulation and clamping tape is porcelain; said insulation tape is of porcelain or mica.
    [0003] Additionally, said outer casing and said internal frame are of non-magnetic permeable stainless steel. Additionally, the inner surface and the outer surface of said inner frame are provided with an insulating layer resistant to high temperature; said high temperature resistant insulating layer is made of mica or organic silicon insulating material. With regard to the outer casing of the electromagnetic coil, it is metallic; a game is open on the outer casing to pass through the upper part and the lower part of the outer casing; said game is connected and fixed by the insulation and clamping band. Additionally, said insulation and clamping tape is porcelain. Additionally, said outer casing is of non-magnetic permeable stainless steel.
    [0004] Regarding the internal framework of the electromagnetic coil, it is metallic; a clearance is opened on the internal framework to cross the upper part and the lower part of also an isolation bar to the internal frame. She including incorporating in the game.
    [0005] Additionally, porcelain or mica. Additionally, said insulation strip is in said internal frame is stainless steel not magnetic permeability; the surface of said internal framework is provided with an insulating layer; said insulating layer is made of insulating material and resistant to high temperature. The present invention is characterized by the following advantages and benefits: Currently, only the air cooling method is applicable to cooling the electromagnetic coil components of the control rod drive mechanism by causing the complexity of the upper flange structures. of the reactor. To simplify the structure at the top of the reducer, the present invention provides a high temperature electromagnetic coil insulating structure at high temperature. The present invention adopts metallic materials to form the outer casing and coil framework to essentially solve such difficulties as softening, deformation, high temperature crack susceptibility of the nonmetallic coil framework, and the like. Thanks to the present invention, it is capable of considerably improving not only the service life of the electromagnetic coil, the high temperature resistance, the integral resistance, but also the vibration resistance, and the humidity resistance. If the electromagnetic coil with this insulating structure is applicable to the drive mechanism of the control rods of the reactor, it is capable of long-term operation provided there is no air cooler in the high temperature environment of nearly 400 ° C, to cancel the additional cooler still necessary to the drive mechanism of the control rods to thereby simplify the structure at the top of the reactor. However, the harmful vortex is likely to be produced between the outer casing of the electromagnetic coil and the frame during operation; to prevent vortex, the cutting clearance is implanted between the outer casing and the frame by inserting the high temperature resistant insulating tape and the insulation and clamping band to prevent vortex formation and guarantee the normal operation of the electromagnetic coil. Currently, the electromagnetic coil of the air-cooled control rod drive mechanism makes it possible to operate in the environment at a temperature of less than 200 ° C to meet the 60-year service life requirements. However, if the electromagnetic coil is operating directly in the environment almost 400 ° C, the service life will be reduced considerably until the rapid failure for a few days due to destruction of the insulating structures. The present invention solves this problem well to make the electromagnetic coil of the drive mechanism of the control rods to operate at high temperature have a fairly long service life.
