1.背景信息 Background：
隨著電力工業(yè)的發(fā)展，對設(shè)備的可靠性要求越來越高。以往人工巡視設(shè)備的方法已逐漸弱化，在這種條件下，高壓設(shè)備的無線測溫系統(tǒng)應(yīng)運(yùn)而生。這種技術(shù)是將內(nèi)置電池和無線發(fā)射模塊的測溫傳感器安裝于各測溫點(diǎn)，由于其體積小，且無需任何接線，其電氣質(zhì)量可以得到保證。傳感器周期性的將測溫?cái)?shù)據(jù)無線發(fā)送至接收單元，接收單元可聯(lián)網(wǎng)將數(shù)據(jù)送至主站，以此實(shí)現(xiàn)一個(gè)區(qū)域系統(tǒng)的電氣溫度監(jiān)測。
目前我國許多地方的電網(wǎng)公司、變電站、鋼鐵公司等都已在高壓設(shè)備上采用這種無線測溫監(jiān)測技術(shù)。
電氣接點(diǎn)在線測溫裝置適用于高低壓開關(guān)柜內(nèi)電纜接頭、斷路器觸頭、刀閘開關(guān)、高壓電纜中間頭、干式變壓器、低壓大電流等設(shè)備的溫度監(jiān)測，防止在運(yùn)行過程中因氧化、松動(dòng)、灰塵等因素造成接點(diǎn)接觸電阻過大而發(fā)熱成為隱患，提高設(shè)備質(zhì)量保障，及時(shí)、持續(xù)、準(zhǔn)確反映設(shè)備運(yùn)行狀態(tài)，降低設(shè)備事故率。
With the development of power industry, the safety and reliability of equipment are highly demanding. In the past, the method of manual inspection equipment has been gradually weakened, under this condition, the wireless temperature measurement system of high voltage equipment came into being. This technology is to install the temperature sensor with built-in battery and wireless transmitting module at each temperature measuring point. Because of its small size and no connection, its electrical safety can be guaranteed. The sensor periodically sends the temperature measurement data wirelessly to the receiver, and it can send the data to the main station on a network, so as to realize the electrical temperature monitoring of a regional system.
Currently, many power grid companies, substations and steel companies in China have adopted this wireless temperature monitoring technology on high voltage equipment.
The electric terminal on-line temperature measuring device is using for the temperature monitoring of cable connector, circuit breaker contact, knife switch, high voltage cable intermediate head, dry transformer, low voltage high current and other equipment in high and low voltage switch gear.To prevent excessive contact resistance caused by oxidation, loosening, dust and other factors during operation, heating becomes a hidden danger of safety, to improve the safety and security of equipment, to reflect the running state of equipment in time, continuously and accurately, and to reduce the accident rate of equipment.
