Description
Technical field
The utility model relates to construction of hydropower facilities field, particularly relates to GIS and neutral point of main transformer lightning arrester on-line monitoring device erecting device.
Background technology
Lightning arrester on-line monitoring device, also known as lightning arrester electric current and discharge counter, is one of most important protective device in electric system.This instrument string is connected in arrester ground loop, in high-voltage alternating system with lightning arrester matching used instrument.Milliammeter in lightning arrester on-line monitoring device is for monitoring the persistent current of working voltage by lightning arrester, according to the numerical value of table, can judge whether lightning arrester inside makes moist, the situations such as whether element is abnormal, operation counter then records the superpotential number of times of lightning arrester, namely in normal operation, lightning arrester is subject to an important parameter of lightning impulse number of times statistics, and it can provide for the staff of electric system the important evidence that specific aim lightning arrester tests.
During the 1# unit regulation in the great river man power station of being accepted by Sinohydro Bureau 4 Co., Ltd., find when conventional electrical test is carried out to 330KV switchyard and main-transformer: GIS room narrow space, equipment is intensive, arrange compact, the part SF6 rain glass of switchyard GIS combination electric appliance, twice protection interval pot type gapless metal-oxide lighting arrester on-line monitoring devices and neutral point of main transformer porcelain bushing type zero-clearance Oxide Arrester on-line monitoring device installation site too high (the former distance ground be about 450CM, the latter's distance ground is about 390CM), make equipment cannot observe instrument numerical value run duration patrol officer.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of safe, GIS of conveniently checking meter and neutral point of main transformer lightning arrester on-line monitoring device erecting device.
For solving the problem, GIS described in the utility model and neutral point of main transformer lightning arrester on-line monitoring device erecting device, comprise the lightning arrester on-line monitoring device fixed on the ground by grounding flat steel and the detected electrical equipment be located on support; Described lightning arrester on-line monitoring device is connected with described detected electrical equipment, it is characterized in that: described support is provided with instrument support with ground level direction, and the center of this instrument support is provided with described lightning arrester on-line monitoring device; The bottom of described instrument support is provided with the angle steel be connected with described support, and this angle steel is provided with the hole of 2 solid ground copper bars.
The height on described instrument support distance ground is 390cm.
Described instrument support is bolted described lightning arrester on-line monitoring device.
The utility model compared with prior art has the following advantages:
1, due to the utility model medium-height trestle being provided with instrument support with ground level direction; the center of this instrument support is provided with lightning arrester on-line monitoring device; therefore; not only effectively prevent the accident potential that climbing equipment causes because checking meter from occurring; and facilitate operations staff's tour; preventing lightning arrester on-line monitoring device numerical value to copy because leaking, copying by mistake and affecting the quality of judgment device and element; improve the reliability of equipment safety operation simultaneously; make mounting process more attractive in appearance, save material, and make electrical primary equipment obtain reliably protecting in electric system.
2, the utility model structure is simple, safe and practical.
Accompanying drawing explanation
