A catenary deicing system

Abstract

The invention discloses a catenary deicing system, which includes an icing sensor, a deicing machine, a control circuit board, and a converging node. The icing sensor is installed at the position where the catenary cable is connected with the horizontal pull rod, and is used for detecting icing of the catenary In some cases, the de-icing machine is installed on the wrist arm to de-ice the contact wire or catenary cable, and the control circuit board is installed next to the de-icing machine to receive the information collected by the icing sensor and the railway dispatching center. command information, and control the work of the deicing machine according to the command information. A converging node is set up next to the catenary to gather the information collected by the icing sensors in the line interval, and transmit the information to the railway dispatching center, which is dispatched by the railway The center sends deicing instructions to the deicing machine, controls the deicing machine to apply vibration to the contact wire or catenary wire, and forces the ice coating to fall through the vibration mechanical wave transmitted to the contact wire or catenary wire.

Description

technical field [0001] The invention relates to the field of catenary deicing, in particular to a catenary deicing system. Background technique [0002] With the rapid development of modern science and technology, my country's electrified railway construction has achieved leapfrog development. At present, the railway department attaches great importance to the safe operation of electrified railways. Icing accidents often occur on the catenary of electrified railways in my country, which has a very bad impact on the rapid development of electrified railways, especially in cold winters. When there are no trains passing by the railway for a long time, the catenary is easily surrounded by ice. This may make it difficult for the pantograph to obtain power, which poses a threat to the safe operation of the train. After the catenary is iced, the catenary equipment not only bears its own weight, but also bears the pressure brought by the ice. Moreover, the environment in which the...

Problems solved by technology

Moreover, the environment in which electrified railways are located is very harsh, and under the action of strong winds, the bearing load of the catenary is greatly increased

When the load on the catenary exceeds the design standard, the catenary may break due to excessive tension of the wires, threatening the safe running of the train

In addition, the icing of the catenary will also reduce the conductivity of the pantograph when it is in contact with the current, which will cause arcing of the catenary, and eventually burn the pantograph and the contact wire

However, the icing of catenary will also cause the phenomenon of bowing, which will damage the pantograph.

[0003] In the past, people usually used the mechanical deicing method, that is, manually knocking on the catenary, so that the basic net was forced to vibrate, so that the ice fell off.

However, this deicing effect is not ideal, which increases the labor intensity of the staff, and may cause certain damage to the catenary

However, the existing high-current ice-melting method needs to waste a large amount of electric energy and is inconvenient to operate; the AC-DC short-circuit ice-melting must first cut off the normal power transmission of the catenary in a short time, and if the control is not good, the contact line will be damaged; Ice will generate high-frequency electromagnetic waves, thereby interfering with the normal communication of other electrical equipment
