Embodiment 1

[0026] see figure 1 , a load monitoring and ambient temperature monitoring method for an opening and closing station, comprising the following steps:

[0027] Step 101: The first temperature sensor installed on the equipment collects the equipment temperature signal; the second temperature sensor installed in the switchgear space collects the ambient temperature signal, and the third temperature sensor installed on the A-phase line is used to collect the A-phase temperature signal, the fourth temperature sensor arranged on the B-phase circuit is used to collect the B-phase temperature signal, and the fifth temperature sensor arranged on the C-phase circuit collects the B-phase temperature signal;

[0028] Step 102: The equipment temperature signal, ambient temperature signal, A-phase temperature signal, B-phase temperature signal, and C-phase temperature signal are all sent to the server through the wireless module, and the server receives the aforementioned equipment temperat...

Abstract

The invention discloses a method for monitoring load and ambient temperature of a sub-section post. The method for monitoring load and ambient temperature of the sub-section post adopts a device temperature signal, an ambient temperature signal, an A phase temperature signal, a B phase temperature signal and a C phase temperature signal to perform synthetic judgment and then transmits an alarm signal. The method of the invention adopts an alarm mode having complete functions, and, when one device goes wrong, the method can timely and accurately find out the fault. Furthermore, the selection of various temperature values in a system enables the alarm accuracy to be higher. Compared with the current system, the method for monitoring load and ambient temperature of the sub-section post can let people know the temperature conditions of various lines and provides first-hand materials to reasonable management of device inspection tour, infrared temperature measurement and state maintenance.

Description

【Technical field】 [0001] The invention relates to the field of power transmission and transformation equipment, in particular to a load monitoring and ambient temperature monitoring method of a switching station. 【Background technique】 [0002] With the development of the economy, the power load continues to rise, and the grassroots management units urgently need to grasp the load operation of the outlets of the switching stations within their jurisdiction. In the switchgear, transformers, circuit breakers, isolating switches, cables and other equipment are equipped with wireless temperature sensors. Sensors, these data are sent to the wireless data base station through the existing communication network of the substation, and then transmitted to the main station to establish a real-time temperature system for the substation equipment. [0003] Although the system has been established, the data has not been fully utilized, resulting in imperfect functions of the existing mon...
