Description
Technical field
The present invention relates to a kind of power equipment, i.e. a kind of bilateral lossless ground connection distribution change platform.
Background technology
Distribution becomes the abbreviation that platform is distribution transformer platform on post, and distribution becomes platform and is fitted with transformer, transformer inputs
Connect high-tension line, claim high-pressure side, its output termination low-voltage circuit, claim low-pressure side.Distribution becomes platform to be needed often to safeguard, upkeep operation
Risk is larger, and attendant's electrification accident happens occasionally.In order to solve this problem,《Electric industry safety in production code》In bright
Literary composition regulation distribution becomes must high-low pressure both sides hanging earthing conductor during platform operation.But existing distribution becomes platform does not have the position of hanging earthing conductor,
When distribution becomes platform maintenance, high-pressure side ground wire is suspended on transformer high-voltage bushing and device clamp junction, low-pressure side is grounded
Line is suspended at low-voltage cable tie point in low-tension distribution box.The method is easily caused distribution transformer bushing and damages, and is
The potential safety hazard of distribution transformer.
Content of the invention

Platform.
Above-mentioned purpose is realized by technical scheme below：Develop a kind of bilateral lossless ground connection distribution become platform, also include be
By change platform, high-pressure side, transformer, low-pressure side, except that：Described high-pressure side is provided with high-voltage ground wire articulated device, described low pressure
Side is provided with low-voltage ground wire connector, and high-voltage ground wire articulated device therein has the bushing being connected with high-voltage line, bushing
One mounting ring of upper support, is provided with insulator string, insulator string lower end is arranged on high-tension electricity post by connecting plate below bushing
On cross-arm, low-voltage ground wire connector is to install the sky with overcurrent tripping function in setting low-pressure cabinet, low-pressure cabinet below transformer
Air cock and double-throw disconnecting link, double-throw disconnecting link itself is connected with low-pressure side, engages with the load side of transformer upwards, downward and low
Pressure ground terminal engages.
The invention has the beneficial effects as follows：During operation, high-voltage ground wire is articulated on high-tension side mounting ring, low-pressure side double
Throwing disconnecting link is left behind and is engaged with low-voltage ground wire end, you can meets the requirement becoming platform operation bilateral ground connection, improves security performance, and has
Have structure to be simple and convenient to operate, be easily installed, material-saving, take up an area less the features such as.
