Abstract
The utility model provides an ice melting device for power transmission lines, which comprises a rectifying transformer, matched impedance, a twelve-pulse rectifier and a regulation control system. The rectifying transformer and the regulation control system which are connected in parallel are electrically connected with an input end of the twelve-pulse rectifier, and two ends of the matched impedance are respectively electrically connected with an anode and a cathode of an output end of the twelve-pulse rectifier. The ice melting device performs ice melting processing on the power transmission lines after the power transmission lines are covered with ice so as to reduce on-site switching operation, avoids load transfer of a power grid, can realize simultaneous ice melting of multiple power transformer substations and multiple power transmission lines of the integral power grid without serial connection and matching of the lines, greatly reduces tower collapse and line breakage after the power grid is covered with the ice, and has the advantages of simple structure, convenience in use and high practicality.
Description
Technical field
The utility model relates to a kind of transmission line deicing device, belongs to the electrical engineering technical field.
Background technology
Form at transmission line and in time it to be carried out ice-melt in the icing and handle, peel off or eliminate icing, prevent that circuit from falling tower and broken string, guarantees that the safe operation of transmission line is very necessary.Yet the deicer that adopts is a kind of deicing device that utilizes the design of ac short circuit method at present.Use this device will apply circuit series connection coupling, load transfer and a large amount of on-the-spot grid switching operations, very complicated, operating difficulties can not launch on electrical network, so be difficult to protect effectively the security of operation of electrical network comprehensively and effectively.
Summary of the invention
The utility model provides a kind of simple in structure, easy to use, practical transmission line deicing device at the deficiencies in the prior art.
Technical solution of the present utility model is: a kind of transmission line deicing device, it is made up of rectifier transformer, matched impedance, 12 pulsating wave rectifier and regulation and control system, and wherein said rectifier transformer electricity in parallel with regulation and control system connects the input of described 12 pulsating wave rectifier.Electric respectively positive pole and the negative pole that connects the 12 pulsating wave rectifier output end in the two ends of described matched impedance.
The transmission line of this device after to icing carries out ice-melt to be handled, to reduce on-the-spot grid switching operation, avoid network load to shift, do not need circuit series connection coupling promptly to realize the changeable power station of full electric network, the ice-melt simultaneously of many transmission lines, reduce the incidence of the broken string of falling tower accident behind the electrical network icing greatly; It has simple in structure, easy to use, practical advantage.
Description of drawings
Fig. 1 is the structured flowchart of the utility model embodiment 1;
Fig. 2 is the structured flowchart of the utility model embodiment 2.
Embodiment
As shown in Figure 1, the transmission line deicing device of this embodiment of the utility model, its Chinese Hengyang of rectifier transformer 1 employing Hengyang Transformer Co., Ltd., Tebian Electric Co. produces the ZS-4600/10 type, capacity is the rectifier transformer of 4600kVA; Its matched impedance 2 adopts Hunan China to economize the pure Power Tech Corp. Inc. of remittance and produces R1000 type impedance matching box; 12 pulsating wave rectifier 3 selects for use Hunan China to economize the rectifier of the KYAF-1400/3000 type of pure Power Tech Corp. Inc. of remittance and the joint research and development exploitation of west, Chinese Xi'an electric power rectifier Co., Ltd, input voltage 1200V, output dc voltage 3000V, rated direct current 2000A; Its regulation and control system 4 is also economized the HDC-2008 type control system that the pure Power Tech Corp. Inc. of remittance develops for Hunan China.Above-mentioned rectifier transformer 1, matched impedance 2,12 pulsating wave rectifier 3 and regulation and control system 4 are formed by circuit shown in Figure 1.Wherein rectifier transformer 1 and regulation and control system 4 electricity in parallel connect the input of 12 pulsating wave rectifier 3.The output of this 12 pulsating wave rectifier 3 is by its anodal matched impedance 2 of connecting with negative pole.
As shown in Figure 2, the Chinese Dongguan of rectifier transformer 1 employing Shunte Electric Co., Ltd. of this embodiment produces ZSC9-4600/10.5/2 * 1.2 type rectifier transformers.Drawing materials of matched impedance 2,12 pulsating wave rectifier 3 and regulation and control system 4 with embodiment 1.Connection between above-mentioned rectifier transformer 1, matched impedance 2,12 pulsating wave rectifier 3 and the regulation and control system 4 is also with embodiment 1.But in the present embodiment, the transmission line deicing device of Gou Chenging is two thus, these two device combination couplings, their combination connecting mode circuit as shown in Figure 2 connects, connecting mode is simple, and only need dock the positive pole/negative pole of the 12 pulsating wave rectifier 3 of one of them device with the negative pole/positive pole of the 12 pulsating wave rectifier 3 of another device.
This device is applicable to that the transmission line behind the icing is launched DC ice melting to be handled, to avoid behind powerline ice-covering broken string even the accident of falling the tower taking place.
