Problems solved by technology

[0002] At present, transmission lines in northern Guangdong are covered with ice. Mobile or fixed ice-melting devices are used for DC melting of short-circuited transmission lines. There is no standard short-circuit tool at the end of the line. Generally, the three-phase is simply short-circuited with screws and nuts. , due to the small contact area, the local heating of the short-circuit point during the ice-melting process is serious, causing damage to the transmission line clamp equipment, and posing a safety hazard to the normal operation of the equipment
[0003] To sum up, the objective shortcoming of the prior art is that in the process of melting ice, the end of the line lacks an effective and safe short-circuiting tool

Embodiment 1

[0032] The transmission lines in northern Guangdong are often covered with ice when the rainy and snowy weather comes. The existing technology uses mobile or fixed ice-melting devices to melt the short-circuited transmission lines in direct current. There is no effective and safe standard short circuit at the end of the line. Connecting tools will cause local overheating and seriously damage the service life of the lead clamp.

[0033] figure 1 It is a schematic diagram of the direct current melting ice shorting tool provided by the embodiment of the present invention.

[0034] refer to figure 1 , the DC ice-melting short-circuit tool includes: a transmission line clamp device and an ice-melting short-circuit board 100 connected to the transmission line clamp device, wherein the transmission line clamp device includes a three-phase lead clamp 200;

[0035] A connection device 300 is provided on the ice-melting short-connection plate 100 for increasing the contact surface of ...

Embodiment 2

[0056] The DC ice-melting short circuit device includes the DC ice-melting short-circuit tool as described in Embodiment 1, and also includes a wireless communication device for sending a warning message to the terminal when the temperature information of the ice-melting short circuit board exceeds a preset threshold. Module 600.

[0057] Specifically, when the temperature of the DC ice-melting short-circuit device rises and overheats, it is very dangerous for the ice-melting operation. However, the prior art lacks a DC ice-melting short circuit that can detect such problems and provide timely feedback to the staff. device. Embodiments of the present invention propose a device to solve this problem.

Abstract

The invention provides an intelligent DC ice-melting shorting tool and device. The intelligent DC ice-melting shorting tool comprises transmission line clamp equipment, an ice-melting shorting plate connected with the transmission line clamp equipment, a monitoring device and an alarm device, wherein the transmission line clamp equipment comprises a three-phase lead clamp; the ice-melting shortingplate used for increasing the contact surface of an ice-melting shorting part is provided with a connection device; the connection device used for being in fit with the three-phase lead clamp is connected with the three-phase lead clamp on the transmission line clamp equipment; the three-phase lead clamp used for implementing shorting while ice melting is carried out on a three-phase line is connected with the three-phase line; the monitoring device used for monitoring temperature information and humidity information of the ice-melting shorting plate and the alarm device are arranged at two ends of the ice-melting shorting plate separately; and the alarm device carries out alarming and warning under the condition that the temperature information and the humidity information exceed a preset threshold. According to the intelligent DC ice-melting shorting tool and device, the contact area of ice-melting sections is increased, the phenomenon that a shade line is damaged by local overheating due to too small contact area is prevented, the safety and the reliability of the ice melting process are also ensured at the same time and the shorting operation is simple and easy.
