High-voltage falling switch contact temperature detection device

Abstract

The invention provides a high-voltage falling switch contact temperature detection device, and belongs to the technical field of detection management in electric power industry. The device consists of a recorder, a multi-mode optical fiber and an optical fiber temperature sensor, wherein the main control chip of the recorder is a singlechip; a clock signal receiving unit is connected to a clock synchronization unit and used for supplying clock signals to a central processing unit (CPU); an information collecting interface is externally connected with the multi-mode optical fiber; the CPU collects temperature information for storage and comparison; results are displayed on a local liquid crystal display, and can be transmitted outwards by virtue of an output interface; and the optical fiber temperature sensor is mounted on a high-voltage falling switch contact, and connected to the recorder by virtue of the multi-mode optical fiber. The high-voltage falling switch contact temperature detection device has the advantages that the recorder of the device real-time records temperature change data of the high-voltage falling switch contact in several days and stores the data in a storage, so that fault information can be supplied when overload or short-circuit faults of transformers occur. Simultaneously, the temperature change information can be exported at any time through a network or by inspectors, so that accident potentials can be discovered timely and the power supply security is ensured.

Description

technical field [0001] The invention belongs to the technical field of detection management in the electric power industry. Background technique [0002] In the power supply facilities of the electric power industry, high voltage drop switches are widely used to ensure the safety of power supply. At the same time, the high voltage drop switch is also an easily damaged device. There are many reasons why the fuse tube of the high voltage drop switch often blows or even burns the contacts of the high voltage drop switch, such as excessive power load, short circuit of the line, poor contact of the contact and so on. Therefore, when the high-voltage drop switch is disconnected, experienced maintenance personnel will often analyze the specific reasons and take corresponding measures to prevent larger power supply accidents. However, the personal experience of the maintenance personnel alone cannot guarantee the accuracy of the judgment. If the real-time monitoring data of the po...

However, the personal experience of the maintenance personnel alone cannot guarantee the accuracy of the judgment. If the real-time monitoring data of the power supply line for a period of time before the fault occurs can be provided, the law of the accident can be found according to the trend of these data changes, and then for accurate troubleshooting. Hidden failures create favorable conditions
