Heinemann®GJ1P Series Circuit BreakersDESCRIPTIONOptional Low-Voltage Shunt for Current MeteringEaton Corporation’s Cutler-Hammer series of Heinemann GJ1P breakers offer high quality circuit protection for DC applications from 100 to 1200 Amperes.Their precisely tailored time delays and ability to interrupt high currents makes them ideally suited for critical applications. On overloads exceeding 1000 – 1400% of rating, there is no intentional time delay and the breaker interrupts currents of as much as 25,000 A at 65V DC.An optional shunt (25 or 50millivolt full scale) permits metering of current. Since the shunt output is low voltage,light-gauge wiring can be used from shunt to meter.Indication may be displayed inpercent, watts, safe/danger or other dial calibrations. In addition, the busbar is available in two versions:Standard Size and Reduced Size. Contact your Eaton Sales Representative for more information.Precision Current Equalization (PCE) Circuit BreakersGJ1P breakers rated 250 to1200 A are built in parallel construction. Conventional parallel pole breakers can experience uneven current distribution because of variations in internalresistances. This condition can result in nuisance tripping since the higher current in one parallel branch has the same effect as an overload on the sensing element in that branch. Proprietary Precision Current Equalization (PCE)circuit breakers, on the other hand, allow for differences in internal resistances byautomatically distributing the current equally through the parallel current sensing elements, minimizing the danger of nuisance tripping.The UL listed series GJ1P (UL489) models are available in a choice of fast, medium or slow response times to accurately match load conditions. They can be ordered in “series trip ”, “mid-trip ” and “switch only ”constructions and are available front- or back-mounted, front- or back-connected, with optional auxiliary switches for signaling.HYDRAULIC-MAGNETIC BENEFITSThe magnetic/hydraulic load-sensing and time delaymechanisms used in GJ1P breakers are insensitive to changes in ambient or enclosure temperature.Therefore, GJ1P circuitbreakers are suited for service conditions encountered in telecommunications,transportation, air conditioning and other outdoor or “heat-loaded ” equipment.SPECIFICATIONSStandard Current Ratings:100, 125, 150, 175, 200, 225,250, 300, 350, 400, 450, 500,600, 700, 800, 900, 1000,1100, 1200 A.Standard Maximum Voltages:160V DC up to 700A65V DC from 701 to 1200A Breakers will be labeled with standard maximum (UL) voltage unless otherwise specified.Special Current Ratings:Any integral rating between 100and 1200 A DC. Consult factory for ordering information and metering shunt restrictions.Interrupting Capacities:UL Listed:10,000 A @ 160V DC 25,000 A @ 65V DC Non-UL:14,000 A @ 160V DC.Operating Temperature Range:-40°C to +85°C.Approximate Weight:1-pole (100-225A) 1.13kg (2.5lbs)2-pole (250-400A) 2.27kg (5lbs)3-pole (450-700A) 3.40kg (7.5lbs)4-pole (701-800A) 4.54kg (10lbs)5-pole (801-1000A) 5.67kg (12.5lbs)6-pole (1001-1200A) 6.80kg (15lbs)Weight may vary based on shunt and busbar.APPROVALSUL Listing:GJ1P breakers are UL listed per UL489.

TRIP DELAY AT 25ºCTIME DELAYCHARACTERISTICSTime delay, in all models,is inversely proportional to the magnitude of the overload, adjusting automatically to limit transient power to the load. On overloads exceeding 1,000 –1,400%, the circuit breaker trips without any deliberately imposed delay.Curve 1.Standard time delayis furnished unlessanother optional delay is specified. It is thepreferred characteristic for use where the load is composed of both resistive and inductive components.Curve 2.Medium time delayis for general usein mixed (inductive and resistive) circuits where the breaker rating is matched to the current carrying capacity of the mains.Curve 3.Short time delaypermits a very brief delay period before tripping.Curve P .Non-time delay breakersare available forapplications which cannot tolerate even brief transient overloads.These breakers have no time delay mechanism other than that imposed by the coil self-inductance and the inertia of the mechanism.Tripping specificationsThe time delay curves depict breaker response time vs. percent of rated load with no preloading.The function is plotted at an ambient temperature of 77°F (25°C) with the breaker in a vertical or wall-mounted position.Series GJ1P circuitbreakers will carry 100%of rated load continuously.Both time delay and non-time delay breakers may trip between 101%and 125% of rated load,and must trip at 125%and above.3% (sec)Delay 100%125%200%400%600%800%1000%Delay Max.1no trip 1100150206 1.7.065Delay Min.1no trip 110224 1.1.01.008Delay Max.2no trip 110153.8.28.055Delay Min.2no trip 12 2.5.5.18.01.008Delay Max.3no trip 10.8.19.08.047.038Delay Min.3no trip.44.13.03.015.01.008STANDARD FRONT-CONNECTED CONSTRUCTIONWire Range #6 to 250 MCM74.59(2.938)76.20(3.000)Aux.

• 调频就是用调制信号x去控制高频载波信号的频率。
常用的是线性调频，即让调频信号的频率按调制信号x的线性函数变化。调频信号us的一般表达式可写为：式中 Wc ── 载波信号的角频率； Um ── 调频信号中载波信号的幅度； m ── 调制度。图X3-2绘出了这种调频信号的波形。图a为调制信号x的波形,它可以按任意规律变化; 下图为调频信号的波形.

2. 在接收到我们所需收听的电台高频电波后，下一步就是把“搭载”在电波上的声音信息取下来，这个“搭载”过程叫调制，那么现在把声音信号取下来则称为解调。解调是通过特别设计的电子线路来完成的。调制的方式有调幅,调频,调相，相对应的，解调的方式或采用的电子线路也是不相同的。从天线上直接接收到的无线电信号是非常微弱的，在通过调谐电路后还需经过放大电路放大到一定幅度才能送往解调电路。 3. 从无线电波上解调出来的声音信息此时还是一种幅度很低的电信号，我们人耳是听不到的，还需用功率放大电路将其放大，再通过喇叭或耳机才能还原成我们真正能听到的声音。

通常无线电波所指的是从极低频3Hz到极超高频的顶点30GHz（Giga Hertz），国际短波广播波段无线电广播和电视无线电波传播 AM: 中波广播使用的频段大致为526.5--1606.5kHz 短波广播使用的频段约为2.3--26.1MHz FM: 频率约为87--108MHz
调频(FM)与调幅(AM)
• 信号的调制
在信号调制中常以一个高频正弦信号作为载波信号。一个正弦信号有幅值、频率、相位三个参数，可以对这三个参数进行调制，分别称为调幅、调频和调相。也可以用脉冲信号作载波信号。可以对脉冲信号的不同特征参数作调制，最常用的是对脉冲的宽度进行调制，称为脉冲调宽。
