Description

Technical Field

[0001] The present application relates to the field of electric power engineering, and specifically to electric power insulation fireproof material technology. Background Art

[0002] Power insulation fireproof plugging glue filling technology is widely used in power systems, especially in key locations such as cable penetration holes, junction boxes, cable trays, etc., to prevent the spread of fire and provide electrical insulation protection. This technology ensures the safe operation of the power system by filling and plugging these potential fire source propagation paths.

[0003] In the prior art, the fireproof sealing glue for power insulation uses polyurethane-modified silicone materials, which have significantly improved performance and have excellent high temperature resistance, low temperature resistance and chemical corrosion resistance. At the same time, modified dimethyl vinyl siloxane is also used, which performs well in improving the flexibility and weather resistance of the material. After the above-mentioned modification design, the fireproof sealing glue for power insulation can be cured within 10 to 15 days after being exposed to the air, and the high temperature resistance of the cured product reaches 550 to 600°C.

[0004] However, some key parts are difficult to construct due to complex structures or curved holes, resulting in insufficient contact between the power insulation fire-proof sealing glue and the air, and the fast curing characteristics of the power insulation fire-proof sealing glue cannot be brought into play.

[0005] Therefore, developing a new implementation method for electric power insulation fireproof sealing glue potting material so that the curing speed of electric power insulation fireproof sealing glue potting can be controlled has become a key requirement for current technological development. Summary of the invention

[0006] The purpose of the present invention is to provide a fireproof plugging glue for electric insulation to solve at least one of the above technical problems.

[0007] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0008] A controllable curing implementation method for electric power insulation fireproof plugging glue, which is provided with electric power insulation fireproof plugging glue, is characterized in that:

[0009] The power insulation fireproof plugging glue adopts fiber-reinforced plugging glue, and the fiber-reinforced plugging glue components include organic silicon base material, fireproof additives, high temperature resistant fillers, and environmentally friendly flame retardants;

[0010] The silicone base is also doped with a fiber web in the form of fragments as a filler;

[0011] The fiber mesh is woven using aramid fibers as warp and weft;

[0012] Aramid fiber as one of the warp and weft has a composite layer of ferroferric oxide powder;

[0013] Aramid fiber, which is another one of the warp and weft threads, has a graphite powder composite layer;

[0014] The fiber-reinforced plugging glue is packaged in an airtight glue cartridge as a glue injection cartridge for curing;

[0015] The implementation method includes the following steps:

[0016] Step S1, dust removal: use compressed air to remove dust from the parts to be cured, the parts to be cured include but are not limited to cable penetration holes, junction boxes, cable trays, and remove floating dust on the surface of the parts to be cured;

[0017] Step S2, oil cleaning: spray the part to be cured with a degreasing spray with self-volatile properties, let it stand for 5 to 10 minutes, and then use compressed air to blow the part to be cured again to remove the residue of the degreasing spray;

[0018] Step S3, glue injection: the sealing film of the glue outlet at the front end of the glue injection cylinder is cut off, and the glue outlet is connected to the glue dispensing needle through a threaded connection; the glue injection cylinder is installed on a glue cylinder glue dispenser, and the fiber-reinforced plugging glue is squeezed out of the glue dispensing needle through the glue cylinder glue dispenser, and evenly injected into the part to be cured;

[0019] Step S4, heating and curing: heating the colloid injected in step S3 by using an electric field induction heating curing process;

[0020] A device for controllable curing of electric sealant is provided, comprising a device housing, a hand-held handle is provided on the device housing, and a telescopic mechanism is installed in the device housing;

[0021] It includes a sealant electromagnetic induction heating plate, the sealant electromagnetic induction heating plate has an electromagnetic heating system, and the sealant electromagnetic induction heating plate is fixed on the device housing;

[0022] It also includes an electromagnet system, the electromagnet has a magnetic core, a coil is wound around the magnetic core, the coil is connected to a power supply device that outputs alternating current as a magnetic field controller, and the electromagnet system is fixed to the telescopic end of the telescopic mechanism;

[0023] Open the telescopic mechanism, start the electromagnetic heating system, and place the sealant electromagnetic induction heating plate close to the plugging glue at a distance of 2 to 5 cm. The warp or weft with the graphite powder composite layer in the fiber mesh makes the fluid glue conductive, and then the colloid is heated in the electromagnetic heating system. The output power of the electromagnetic heating system is adjusted to control the heating speed and temperature of the fluid glue, thereby controlling the curing speed of the fiber-reinforced plugging glue.

[0024] The method also includes step S5, vibration curing: the device for controllable curing of the electric sealant prepared in step S4 opens the telescopic mechanism, starts the electromagnet system, and brings the magnetic core 2 to 6 cm close to the part to be cured. The magnetic field of the electromagnet system interacts with the warp or weft of the fiber mesh compounded with ferroferric oxide powder, driving the fiber mesh to vibrate, thereby stirring the plugging and pouring glue, thereby accelerating the curing of the plugging and pouring glue.

[0025] In the above design, the purpose of using the fragmented fiber mesh as a filler is to achieve controllable curing speed. As one of the warp or weft threads, the aramid fiber is compounded with graphite powder, which makes the fluid glue conductive. In the high-frequency alternating magnetic field generated by the electromagnetic induction device, eddy currents will be generated to generate heat, thereby increasing the ambient temperature during the curing of the power insulation fireproof sealing glue. The beneficial effect is that the heating rate and the temperature of the conductive fluid glue can be controlled by the frequency and power of the alternating magnetic field, thereby controlling the curing efficiency and curing speed of the plugging glue.

[0026] The beneficial effect of implementing step S1 of the method is to remove floating dust, so that the contact between the part to be cured and the power insulation fireproof sealing glue is more firm.

[0027] The beneficial effect of implementing step S2 of the method is to remove the oil stains, colloid residues and the like that may remain on the part to be cured, so that the combination of the part to be cured and the plugging glue is more firm.

[0028] The beneficial effect of implementing step S3 of the method is that the glue cartridge glue dispenser can be used as a glue dispenser for the power insulation fireproof sealing glue, so as to facilitate the curing operation of the power insulation fireproof sealing glue.

[0029] The beneficial effect of implementing step S4 of the method is that the electromagnetic heating system is used to control the fluid glue to generate eddy current, thereby controlling the heating rate and temperature during curing to achieve controllability of the curing speed.

[0030] The beneficial effect of implementing step S5 of the method is that, as the other of the warp or weft, the aramid fiber is bonded with ferroferric oxide powder, which is magnetic and can drive the fiber net to vibrate under the action of the alternating magnetic field. The beneficial effects are: first, the vibration of the fiber net can play a stirring role, so that the components of the power insulation fireproof sealing glue are better mixed; second, the vibration of the fiber net can play a role in removing bubbles in the colloid and improving the quality of curing; third, the vibration of the fiber net can make the contact between the fiber net and the power insulation fireproof sealing glue more firm and eliminate surface tension.

[0031] Furthermore, the frequency of the alternating current passed through the induction coil is 20-40kHz, and the power is 100-300W.

[0032] In the above design, the frequency of the alternating current is in the range of 20-40kHz. The high-frequency electromagnetic induction in this range is sufficient to generate eddy currents in the warp or weft threads bonded with graphite powder. The power is controlled at 100-300 watts, which can keep the temperature at 20-50°C, thereby promoting the curing speed without damaging the colloid of the power insulation fireproof sealing glue due to excessive temperature.

[0033] Furthermore, the frequency of the electromagnet with cyclic reversal of magnetic polarity is between 5 and 30 Hz.

[0034] In the above design, the function of the frequency of the magnetic polarity reversal cycle is to drive the fiber web to vibrate, so as to achieve stirring, remove bubbles, and make the contact between the web and the colloid more firm. The fiber web is mixed in the fluid colloid, and its excessive vibration will be eliminated by the colloid resistance. Therefore, there is no need to vibrate too fast. The frequency of the magnetic polarity reversal cycle is 5 to 30 Hz, which can meet the vibration needs without consuming more energy.

[0035] Furthermore, the organosilicon base material of the fiber-reinforced plugging glue is also doped with gas storage particles detonated by magnetic force, and the gas storage particles are used as fillers;

[0036] The gas storage particle has an airtight membrane filled with air at 1.15 to 1.3 atmospheres, and also includes a magnetic needle;

[0037] The magnetic needle includes a needle tip and a needle body, wherein the needle tip is made of a soft magnetic material and the needle body is made of a non-magnetic material;

[0038] The method also includes step S6, magnetic detonation: a device for controllable curing of electric power sealant is prepared, the telescopic mechanism is opened, the electromagnet system is started, the magnetic core is brought 3 to 5 cm close to the colloid of the plugging and potting glue, and the magnetic needle tip is pulled through the magnetic field of the electromagnet system to pierce the membrane of the gas storage particles, thereby releasing the air in the gas storage particles inside the fiber-reinforced plugging and potting glue, and the water molecules contained in the released air chemically react with the cross-linking agent inside the fiber-reinforced plugging and potting glue to form a three-dimensional cross-linked network, thereby accelerating the curing efficiency and speed of the electric power insulation fireproof plugging and potting glue.

[0039] In the above design, in order to further improve the curing speed, gas storage particles are added to the fiber-reinforced plugging glue, the gas storage particles are filled with air, and magnetic needles for detonating the gas storage particles are arranged in the gas storage particles. An electromagnet system is used around the part to be cured, and the magnetic needle tip is guided by the magnetic field to pierce the membrane of the gas storage particles, thereby releasing the air in the gas storage particles inside the fiber-reinforced plugging glue. The beneficial effect is to accelerate the curing efficiency and speed of the power insulation fireproof sealing glue. DETAILED DESCRIPTION

[0060] Open the telescopic mechanism, start the electromagnetic heating system, and place the sealant electromagnetic induction heating plate close to the plugging glue at a distance of 2 to 5 cm. The warp or weft of the fiber mesh with a composite layer of graphite powder makes the fluid glue conductive, thereby heating the glue in the electromagnetic heating system.

[0061] In this embodiment, the purpose of using the fragmented fiber mesh as a filler is to assist in achieving controllable curing speed. As one of the warp or weft threads, the aramid fiber is compounded with graphite powder. The graphite powder is in the silicone base material to form a fluid glue, which causes the fluid glue to have a certain conductivity.

[0067] In this embodiment, the frequency of the alternating current of the special equipment is in the range of 20-40kHz. The high-frequency electromagnetic induction in this range is sufficient to generate eddy currents in the warp or weft threads bonded with graphite powder. The power is controlled at 100-300 watts, and the temperature can be kept at 20-60°C, which can promote the curing speed without damaging the colloid of the power insulation fireproof sealing glue due to excessive temperature.

[0069] The method also includes step S5, vibration curing: the device for controllable curing of the electric sealant prepared in step S4 opens the telescopic mechanism, starts the electromagnet system, and brings the magnetic core 2 to 6 cm close to the part to be cured. The magnetic field of the electromagnet system interacts with the warp or weft of the fiber mesh compounded with ferroferric oxide powder, driving the fiber mesh to vibrate, thereby stirring the plugging and pouring glue, thereby accelerating the curing of the plugging and pouring glue.

[0070] In this embodiment, the beneficial effect of implementing step S5 of the method is that, as the other of the warp or weft, the aramid fiber is bonded with ferroferric oxide powder, which is magnetic and can drive the fiber net to vibrate under the action of the alternating magnetic field. Its beneficial effects are: first, the vibration of the fiber net can play a stirring role, so that the components of the power insulation fireproof plugging glue are better mixed; second, the vibration of the fiber net can play a role in removing bubbles in the colloid and improving the quality of curing; third, the vibration of the fiber net can make the contact between the fiber net and the power insulation fireproof plugging glue more firm and eliminate surface tension.

[0072] In this embodiment, the function of the frequency of the magnetic polarity reversal cycle is to drive the fiber web to vibrate, so as to achieve stirring, remove bubbles, and make the contact between the web and the colloid more firmly. The fiber web is mixed in the fluid colloid, and its excessive vibration will be eliminated by the colloid. Therefore, there is no need to vibrate too fast. The frequency of the magnetic polarity reversal cycle is 5 to 30 Hz, which can meet the vibration needs without consuming more energy.

[0073] Furthermore, the organosilicon base material of the fiber-reinforced plugging glue is also doped with gas storage particles detonated by magnetic force, and the gas storage particles are used as fillers;

[0074] The gas storage particle has an airtight membrane filled with air at 1.15 to 1.3 atmospheres, and also includes a magnetic needle;

The water molecules contained in the released air react chemically with the cross-linking agent inside the fiber-reinforced plugging and potting glue to form a three-dimensional cross-linked network, thereby accelerating the curing efficiency and speed of the electric power insulation fireproof plugging and potting glue.
