Embodiment Construction

[0027] Such as figure 1 As shown, the method of using the cable cover to reduce the interference of communication cables in the substation is as follows:

[0028] 1. Install n conductive copper pillars with a resistance value of 4-5Ω along the horizontal direction on the bottom surface of the cable cover plate 1 on the cable trench connected to the main control room. n is an odd number between 15-21. The laying direction of the trench cable is laid out, numbered from one side to the other as conductive copper column 1, conductive copper column 2...conductive copper column 17; two adjacent conductive copper columns are insulated;

[0029] 2. A conductive copper column, a current-limiting resistor R1 connected in series, an electronic switch, and an energy storage device. The energy storage device is powered by a solar panel ≦100AH. The energy storage device is installed at the head end 101 of the cable cover, and the cable cover The head end of the board is the side close to t...

Abstract

The invention discloses a method for reducing communication cable interference in a substation by adopting a cable cover plate with an aim to achieve the purpose of effectively reducing communication cable interference by placing the cable cover plate optionally in the substation to eliminate interference flux generated by power cables and interference flux generated by self-generated reverse flux integrated power cables. The method includes that n conductive copper columns are mounted on the bottom surface of the cable cover plate along the horizontal direction, and the n is an odd number between 15 and 21; a first conductive copper column is serially connected with a current limit resistor R1, a first electronic switch and an energy storage unit; the second conductive copper column is serially connected with a second current limit resistor R2, and a second electronic switch and the energy storage unit; two ends of the conductive copper column with the largest number are serially connected with a current limit resistor R3 and a milliampere direct-current electronic ammeter; the rest conductive copper columns, with the odd numbers, connected correspondingly to the tail end of the cable cover plate and the conductive copper columns, with the even numbers, connected correspondingly to the head end of the cable cover plate are connected with a grounding grid of the substation; a device used for controlling current collection and switching control of the electronic switches is mounted at the bottom of the cable cover plate.

Description

technical field [0001] The invention relates to a method for reducing the interference of communication cables in a substation by using a cable cover plate. Background technique [0002] At present, communication cables in substations are generally layered with power cables or twisted in pairs to reduce external interference to itself. Since there are many power cables and communication cables in the substation, especially in the smart substations that are gradually popularized, the communication cables are more and more long, and the interference from the outside world is becoming more and more obvious. The important telecontrol information carried by the communication cable in the substation often appears garbled after being interfered, which has a great impact on the normal monitoring and maintenance of the substation. Contents of the invention [0003] The present invention proposes a method for using cable cover plates to reduce the interference of communication cabl...
