Extra-high voltage transformer substation electrified hoisting safety warning device

Abstract

The invention relates to transformer substation safety systems and particularly relates to an extra-high voltage transformer substation electrified hoisting safety warning device. The extra-high voltage transformer substation electrified hoisting safety warning device comprises multiple sets of electrified equipment, a hoisting platform, a hoist and a signal receiving device. A plurality of radarsII are arranged on the electrified equipment and the hoisting platform, and a radar I in induction with the radars II is arranged at the front end of a hoisting arm of the hoist. The signal receivingdevice comprises a converter, a buzzer, a warning light and a power supply, wherein the buzzer, the warning light and the power supply are connected to corresponding connectors of the converter respectively. Distant data are transmitted between the radar I and the converter in a wireless mode. The device is simple in structure, convenient to operate, flexible in transportation and quite suitablefor providing safety warning for adjacent electrified hoisting of extra-high voltage transformer substations. Personnel safety and machine safety are sufficiently ensured. The device is convenient andeffective to use, greatly saves manpower and improves working efficiency.

Description

technical field [0001] The invention relates to a safety system of a substation, in particular to a safety warning device for point hoisting of an ultra-high voltage substation. Background technique [0002] When the power system is partially powered off in the substation for hoisting work, it will encounter situations where hoisting hoisting machinery, wall-lifting bucket trucks and live equipment are close to the safety warning value, and hoisting commanders and guardians cannot patrol. At this time, it is necessary to use the live hoisting safety warning device of the UHV substation to confirm the safety distance in time, alarm when the safety distance is close to the warning value, and remind the on-site operators, commanders, crane drivers, etc., to ensure the safety and reliability of partial power outage construction of the substation. [0003] At present, due to the lack of special live hoisting safety warning devices for UHV substations, when the operators, commande...

AI Technical Summary

Problems solved by technology

[0003] At present, due to the lack of special live hoisting safety warning devices for UHV substations, when the distance between operators, commanders, and crane drivers is too close to the primary live equipment during hoisting and hoisting operations , When moving back and forth, left, right, up and down, it is easy to exceed the safe distance from the live equipment, forming a huge safety hazard

During simultaneous construction operations, there are insufficient command personnel and guardians, and it is impossible to monitor the three-dimensionally closed working surface of the construction operation at the same time
