Description
Technical field
The utility model is related to a kind of power supply, specifically a kind of stable type low pressure shore electric power system.
Background technology
With the application of China's high voltage shore power and fast development, and on April 1st, 2016, Pearl River Delta, length are set up in China's declaration
Triangle, 3, Circum-Bohai Sea waters ship emission control area, the Yangtze River Delta take the lead in implementing most tight ship emission reduction order.Tend to high voltage shore power skill
Art is ripe and is setting up energy saving emission point into pass control zone, and the high voltage shore power power supply for being equipped with different capabilities is the ship that reaches port
Oceangoing ship is powered, and energy-saving and emission-reduction and economic benefit are with obvious effects.According to related environmentally friendly department statistics and shipowner's feedback, in Shanghai, root
According to Shanghai air PM2.5 source resolutions, in local emission source, the mobile sources such as motor vehicle, ship account for 31%, wherein Pollution From Ships account for 8% to
10%.8% to 10% can be reduced using Pollution From Ships after high voltage shore power power supply, expense reduces by 30% to 40% or so；According to communications and transportation
What portion printed and distributed《Pearl River Delta, the Yangtze River Delta, Circum-Bohai Sea（Jing-jin-ji region）Waters ship emission control area embodiment》, from January 1 in 2016
It day rises, conditional harbour can implement the ship lay day that pulls in shore and be higher than existing row using fuel oil etc. of 0.5% m/m of sulfur content
Put the measure that control requires；From 1 day January in 2017, the ship in core port region should be contained in the lay day that pulls in shore using sulphur
Measure the fuel oil of 0.5% m/m；From 1 day January in 2018, lay day is pulled in shore at ship all harbours in emission control area will
Use the fuel oil of 0.5% m/m of sulfur content；From 1 day January in 2019, after ship enters emission control area, it is necessary to use sulfur content
The fuel oil of 0.5% m/m；Before 31 days December in 2019, China will on the basis of assessing ship emission control area's implementation result, into
One step determines that more stringent control measure, including ship enter fuel oil and expansion of the emission control area using 0.1% m/m of sulfur content

Enough according to ship electricity consumption automatic switching reactive compensator, output power factor is set to reach 95% or more, remote high pressure concerned countries
Standard；European-type box fades to harbour bank electricity cabinet and the totally-enclosed busbar of epoxy resin pouring, degree of protection is used to reach IP68;Volume
Small, capacity is big, high pressure, and decompression is small, and loss is low, and overload capacity is strong, and shock resistance is strong, non-maintaining, and operating cost is low, can be in whole day
It waits and is used in environment；Along with China power grid peak, low ebb voltage ripple of power network are big, the output of common stable type low pressure shore electric power
Spread of voltage causes the ship power load service life to substantially reduce；The stable type low pressure shore electric power of our company development ＆ production design
It is soaked with voltage adjustment of on-load isolating transformer using energy-saving oil to be combined with automatic regulation control system, can realize seamless voltage
It adjusts, output voltage stabilization, with ship electricity consumption with frequency, same to phase, the same period, meets《China Classification Society steel seagoing vessel enters grade and builds
Specification》Alternating current generator：Automatic Regulation：Within voltage fluctuation ± 2.5%；Protect warning function perfect, ship electricity consumption personnel are not necessarily to
Worry safety problem, there is interlocking failure, overcurrent, overvoltage, under-voltage, dead electricity, circuit breaker trip (short circuit, electric leakage), the POS, exhausted
Low, fire alarm of edge etc.；It is calculated, gathered data can be calculated using liquid crystal touch screen and PLC Programmable logical controllers,
Realize that overvoltage, overcurrent, under-voltage etc. adjust value protection with breaker itself and match realization duplicate protection;It can using liquid crystal touch screen
Programmed logic controls, and can set up the cryptoguard of multilayer proofing grade, the user of different stage can only enter corresponding login
Picture is controlled, other personnel cannot be introduced into control system and carry out closing/separating brake, greatly strengthen the safe to use of shore electric power.
