Embodiment Construction

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0031] see figure 1 , the substation post insulator long-distance charged deicing method of the present invention comprises the following steps:

[0032] Classify the substation post insulators according to the material, and adjust the parameters of the high-energy laser so that the number of photons per unit area does not exceed the threshold of the number of photons per unit area corresponding to the classification; the adjusted high-energy laser is charged to the correspondingly classified substation post insulators deicing. By controlling the number of photons per unit area, the energy per unit area can be controlled, and long-distance charged deicing can be realized without causing the insulators to burst due to instantaneous temperature rise....

Abstract

The present invention discloses a transformer substation supporting insulator remote electrification deicing method and device. The method comprises the steps of: classifying transformer substation supporting insulators according to materials, according to the classification, regulating parameters of a high-energy laser to a unit area photon number threshold value corresponding to the classification without exceeding the photon number at the unit area; and performing electrification deicing of the transformer substation supporting insulators corresponding to the classification by employing theregulated high-energy laser. The transformer substation supporting insulator remote electrification deicing method and device control the number of the photons in the unit area to achieve controllable energy in the unit area so as not to cause the rising of the instantaneous temperature of the insulators to explode. The transformer substation supporting insulator remote electrification deicing method and device are short in deicing time and long in the electrification deicing distance, do not damage the supporting insulators and have obvious advantages in performances compared to other products.

Description

technical field [0001] The invention relates to the field of power grid protection, in particular to a method and device for deicing long-distance electrification of substation post insulators. Background technique [0002] Large-scale rain and snow freezing is the biggest disaster for the safe operation of the power grid. Icing on the external insulation of substation equipment will lead to flashover of insulators, tripping of lines and outage of substations due to voltage loss, seriously affecting the safe and stable operation of the power grid. During the ice disaster in 2008, many substations of 220kV and above were out of service due to ice flash of pillar insulators; in 2016, Hunan 220kV Lujia Substation and other substations were out of service due to ice flash; The fast charging deicing is of great significance. [0003] The existing deicing methods for substation equipment mainly contain the following types: [0004] (1) Manual mechanical deicing can not be deici...
