Embodiment 1

[0022] An electromagnetic induction melting ice method described in this embodiment is to set at least one insulating ring at the place where the power line is likely to be covered with ice, and an electromagnetic induction ring is arranged outside each insulating ring, and the electromagnetic induction ring is made of electromagnetic induction heating material production. The electromagnetic induction ring is a ring that can be opened and closed, and is made of electromagnetic induction material. A diaphragm pressure sensor is arranged outside the electromagnetic induction ring, and the pressure sensor is connected with an operating mechanism for controlling the opening and closing of the electromagnetic induction ring. When the ice coating on the transmission line reaches a preset thickness, the pressure sensor provides a signal to the operating mechanism, and the operating mechanism closes the electromagnetic induction loop, which then generates heat to melt the ice coating...

Embodiment 2

[0024] An electromagnetic induction melting ice method described in this embodiment is to set at least one insulating ring on the place where the power line is prone to icing, and an electromagnetic induction layer is arranged outside each insulating ring, and the electromagnetic induction layer is an openable , Combined coil, the electromagnetic induction coil is made of electromagnetic induction heating material. A pressure sensor is arranged outside the electromagnetic induction layer, and the pressure sensor is connected with the operating mechanism that controls the opening and closing of the electromagnetic induction coil; The magnetic induction coil is closed, and the electromagnetic induction ring then generates heat to melt the ice; as the ice melts and becomes thinner or disappears, the pressure sensor senses the pressure signal and transmits the signal to the operating mechanism, and the electromagnetic induction coil turns on and stops heating. The ice melting job ...

Embodiment 3

[0026] The electromagnetic induction ice-melting device of an embodiment of the present invention see figure 1 and figure 2 . The electromagnetic induction ice melting device includes an insulating ring 10, an electromagnetic induction ring is arranged on the outer layer of the insulating ring 10, and a pressure sensor 30 is arranged outside the electromagnetic induction ring.

[0027] The electromagnetic induction ring is made of electromagnetic induction heating material, including a split ring 20 and a metal shrapnel 22. One end of the metal shrapnel 22 is hinged to the split ring 20, and the other end can rotate around the hinge. When the fixed end of the metal shrapnel overlaps When connected to the split ring 20, the split ring 20 and the metal shrapnel 22 form a closed ring.

[0028] The opening of the split ring 20 is provided with an insulating protective shell 31, which completely wraps the metal dome 22, prevents rainwater from forming ice coating between the met...

Abstract

The invention discloses an electromagnetic induction de-icing method and an electromagnetic induction de-icing device. At least one insulating ring is sleeved on the part where ice is easily coated on an electric transmission line; an electromagnetic induction layer is arranged outside the insulating ring; a pressure sensor is arranged outside the electromagnetic induction layer and is connected with an operating mechanism for controlling an electromagnetic induction ring or coil to open and close; when the thickness of the ice coated on the electric transmission line is up to preset value, the pressure sensor provides a signal to the operating mechanism, the operating mechanism closes the electromagnetic induction ring or coil, and subsequently the electromagnetic induction ring generates heat to de-ice; and the coated ice is dissolved, becomes thin or disappears, after sensing a pressure signal, the pressure sensor transmits the signal to the operating mechanism, and the electromagnetic induction ring or coil is started and stops generating heat. The thickness of the coated ice on the transmission line can be monitored in real time by the method and the device, and once the thickness of the coated ice is up to the preset thickness, the de-icing device can be started to de-ice, so that the ice is timely removed, and the safety of electric transmission equipment can be fully guaranteed.

Description

technical field [0001] The invention relates to the field of disaster reduction and prevention in power systems, in particular to an ice-melting device and also to an ice-melting method. Background technique [0002] With the rapid development of the economy, the country has increased investment and construction of electric power industry. With the construction of a large number of high-voltage and ultra-high voltage power grids, more and more attention has been paid to the safe and stable operation of transmission lines. High-voltage transmission lines are mostly erected in wild mountainous areas and other places. In cold areas, they are easily affected by freezing weather and are covered with ice. Ice coating on transmission lines will increase the mechanical load on conductors and towers. When the ice coating is severe, it will cause accidents such as line tripping, disconnection, pole collapse, insulator flashover, and communication interruption. Since ice damage accide...
