發電機組與低壓配電柜智能斷路器不互投的原因?

2013/4/30 16:29:56

兩臺變壓器都帶發電機是GCK柜體還帶聯絡柜要怎么切換?

兩路進線柜和中間的聯絡柜有電器連鎖!也就是這三臺柜子斷路器只能同時合閘2個!
就是兩路進線同時工作中間的聯絡就不能合閘,合閘一路進線時中間的聯絡可以合閘,但是第二路進線就不能合閘

東風康明斯發動機怎么增加動力?

想要增加發動機的馬力,在增加油泵供油量的同時也要增加空氣量。加裝增壓機,為了增加氧氣的密度還要加裝中冷器。只有這樣才能增加發動機的動力。

康明斯發動機冷卻液的溫度太低是怎么回事?

看看是不是表不準,或是水溫傳感器有毛病,要是電子風扇的話,看看風扇是不是長轉,再有你的車節溫器摘沒摘下去

康明斯動力換熱器的故障維修?

發電機組與低壓配電柜智能斷路器不互投?

有專門解決雙路電源的安全轉換的空開和輔助控制裝置。發電機和外網的邏輯控制及安全切換,實際上分立元件自己搭也可以,只不過避免并聯的影響和事故。簡單的外網無可啟動發電機,外網來電需要發電機停后主回路切換,外網和發電機都有時電能的指定切換,實際上電控雙投開關和手動雙投刀閘或回路都可以實現。有的系統切換只是部分不能停電的負荷轉換,

怎么樣柴油發電機改裝成全自動的?

在配電房加ATS控制柜,在發電機組上改裝智能控制屏,兩個加起來就可以實現柴油發電機全自動控制了!

發電機并列時智能同期切換裝置的作用是什么?

智能同期裝置作用是控制發電機并列用的,它有手動、自動、半自動切換方式,還有同期和無壓兩種狀況選擇,功能強大,它通過比較系統電壓、頻率與發電機電壓、頻率,發出信號使機端開關兩側參數達到允許并網條件,然后自動撲捉相位達到快速并網

發電機的自同期并列對電力系統的事故處理有沒有好處?

有一點好處。發電機自同期并列比原始的手動并列加快了并網的速度,當電力系統發生震蕩需要一些發電機盡快投入電網,以消除震蕩時,自同期比手動同期快的多了。
發電機雙電源切換裝置和連鎖保護功能每個發電機都有嗎?

一般柴油發電機及其控制箱是沒有此功能的,你說的功能只有雙電源切換柜才有。

幾臺發電機并聯運行并不上是什么回事?

一、主要是并列的條件不滿足
1、相序相同-就是A\B\C對A\B\C-當然安裝時已經對應,這個在運行中不做考慮。
2、電壓相等
3、頻率相等
4、相位相同
  看你的裝置設置,調出同期參數數值,檢查數值設定值是否太小, 檢查四個條件是否滿足要求。
二、其它原因:
    1、調速器設置不當-調速器無擾動,頻率相等但相位始終不同。
    2、發電機監控器故障-檢查電源、信號輸入、控制輸出、通訊等
    3、開關控制電源及合閘電源應正常。
為什么發電機組不能長時間低轉速運行?

三相四線中,零線發熱是什么原因。可以解決嗎?

零線電流過大首先三相負荷是否平衡。盡量平衡三相負載。其次零線是否小的太離譜。

發電機勵磁系統接地現象的原因?

勵磁回路兩點接地現象:
①勵磁電流迅速增大,無功輸出大幅度降低,“轉子過流”保護可能動作 ,“轉子兩地接地”信號亮。
②發電機轉子電壓可能降低。
③機組發生較大振動,發電機可能變為異步電動機運行。

發電機轉子繞組兩點接地故障有哪些危害?
①發電機轉子繞組兩點接地后,相當于一部分繞組短路,兩個接地點之間有故障電流流過,它可能引起線圈燃燒和由于磁路不平衡引起發電機劇烈振動;
②轉子電流流過轉子本體,如果電流大可能燒壞轉子鐵芯
③由于轉子本體局部通過電流,引起局部發熱,使轉子緩慢變形而偏心,進一步加劇振動。
一點接地時,由于不構成回路,故障點無電流流過,可以運行,保護發信號,防止發展成兩點接地。
兩點接地時,兩接地點直接相當于短路,兩短路點之間有很大短路電流流過,造成轉子電流增大,而勵磁電流卻減小,因此無功降低

Two transformers are driven generator houndreds types product as like GCK ark cabinet put oneself in another's position with contact how to switch?

Two ark of road into a line contact in the middle of the cabinet have electrical appliances chain! Is this three circuit breaker cabinet can switch two at a time!

Is the middle of the road into two lines at the same time work contact can not switch, switch can switch among all the way into the line of contact, but the first 2 will not be able to switch into the line

Dongfeng cummins engine how to increase the power?

Want to increase engine power, while boosting pump oil should also increase air volume. Equipped with booster, in order to increase the density of oxygen and installing intercoolers. Only in this way can increase the engine power.

Cummins engine cooling fluid temperature is too low, how be to return a responsibility?

See if table is not allowed, or there is something wrong with water temperature sensor, electronic fan, see if fan long turn, have your car thermostat pick didn't pick it

Cummins power exchanger breakdown maintenance?

Generator sets and low voltage power distribution ark intelligent circuit breaker is not for each other?

Have specific solution to the dual power supply safety transformation of air and auxiliary control unit. Logic control and safety of the generator and the network switch, actually can also be discrete component himself, just avoid in parallel and the influence of the accident. Simple outer net start generators, network calls need generator stop after circuit switching, all network and generators are sometimes designated switch of electric power and electric control actually double throw switch and double knife switches or loop can achieve manually. Some system switching is only partly not power load conversion,

How about diesel generator into a fully automatic?

In the transformer room and ATS control cabinet, control panel on the generator set refitted intelligence, two together can realize automatic control of the diesel generator!

Generator and what is the function of intelligent switching device during this period?

Smart device function is to control the generator tied for use during this period, it has a manual, automatic, semi-automatic switch mode, and in the same period and pressureless choose two kinds of condition, powerful functions, it by comparing the system voltage, frequency, and the generator voltage, frequency, sends a signal to make the machine side switch on both sides of the parameters to allow the interconnection conditions, then automatically capture phase to achieve quick interconnection

Generator's from the same period of power system accident treatment benefits?

There is a little good. Juxtaposed with the generator from the same period than the original manual tied to speed up the speed of interconnection, when need some oscillation generator power system input grid, as soon as possible to eliminate the oscillation, much faster than the same period manually since the same period.

Generator double power switching device and chain protection function each generator has?

Diesel generator and its control box is generally don't have this function, you said function is only available in the ats switch cabinet.

Several generator in parallel operation is not on what is going on?

A, mainly coordinate condition not satisfied

1, the phase sequence is the same - A \ B of A \ B \ \ C C - have corresponding when installation, of course, this do not consider in the run.

2, the voltage is equal to

3, frequency equal to the

4, same phase

See your device Settings, bring up the parameter values at the same period, and check whether the numerical value is too small, check if four conditions meet the requirements.

Other reasons:

1, speed governor governor Settings - no disturbance, frequency but different phase always equal.

2, generator fault monitor - check the power supply, signal input and output control, communications, etc

3, switch power supply and switching power supply should be normal.

Why can't a generating set run low speed for a long time?

Three phase four line, zero line heating is what reason. Can solve?

If zero line current is too large, first of all, the three-phase load balancing. Try to balance the three phase load. Second zero line is little far off the mark.

Generator excitation system earthing phenomenon reason?

Two-point grounding phenomenon of excitation loop:

(1) field current increases rapidly, reduce reactive power output, "the rotor over current protection possible action," dual rotor grounding "signal light.

(2) may reduce the rotor of the generator voltage.

(3) units are great vibration, generators can be run into asynchronous motor.

Generator rotor winding two points earth fault what harm is there?

(1) after the generator rotor winding two-point grounding, equivalent to part of the winding short circuit, two ground fault current flows through between the two, it may cause burning coil and intense vibration caused by the unbalance of the magnetic generator;

(2) the rotor current flow through the rotor body, if the current big may burn out the rotor iron core

(3) local by current due to the rotor body, cause local fever, slow rotor deformation and eccentricity, intensified vibration.

One-point earthing, because do not constitute a circuit, no current flows through the fault point, can run, signal protection, prevent into two-point grounding.

Two-point grounding, two ground directly equivalent to short circuit, there is a lot of short circuit between two short-circuit point of current to flow through, causing rotor current increases, and the exciting current is reduced, so the reactive power is reduced
