5、on has been developed to enable the unified definition, test, and evaluation of thyristortype surge protective device parameters. A thyristor surge protective device limits overvoltages by switchingon and providing a low impedance path to divert the current resulting from the overvoltage. Fixed volt

6、agethyristor surge protective devices have their limiting voltage determined by the manufacturing process.Gated thyristor surge protective devices may have their limiting voltage determined by the reference poten-tial applied to the gate. By connecting the gate in series with the circuit conductors,

7、 overcurrent conditionscan also initiate device switch on and current diversion.Thyristor devices have been used since the early 70s to protect telecommunications equipment againstinduced and conducted overvoltages caused by lightning and ac systems. These devices were specially engi-neered to provi

8、de the required protection function. The device main features were an extended breakdownregion and an abnormally high value of holding current. As a result, many of the conventional thyristor termsand test methods were inadequate for these thyristor surge protective devices. Being a new device varia

9、nt,many existing surge protective device manufacturers and users applied terms and tests used for gas-dis-charge tubes or avalanche junction semiconductor surge protective devices. Compared to these establisheddevices, the thyristor surge protective device has different circuit sensitivities and thi

10、s resulted in poorparameter correlation between users and suppliers.There was a need for a comprehensive thyristor surge protective device test standard that defined terms,detailed appropriate test circuits, and measurement conditions. The Low-Voltage Solid-State Surge Protec-tive Devices Working Gr

11、oup 3.6.2 of the IEEE Surge Protection Devices Committee under took the task ofpreparing such a standard.

24、. Overview1.1 ScopeThis standard applies to two or three terminal, four or five layer, thyristor surge protection devices (SPDs)for application on systems with voltages equal to or less than 1000 V rms or 1200 V dc. These protectivedevices are designed to limit voltage surges on communication circui

25、ts and on power circuits operating fromdirect current (dc) to 420 Hz. The thyristor SPD can be manufactured with unidirectional or bidirectional,symmetrical, or asymmetrical V-I characteristics. This standard contains definitions, service conditions, anda series of test criteria for determining the

26、characteristics of a thyristor SPD. If the characteristics differ withthe direction of conduction, each polarity shall be separately specified.1.2 TestsThe tests in this standard are intended as design tests as defined in B31and provide a means of comparisonamong various thyristor SPDs.NOTEThree ter

27、minal devices may consist of multiple thyristor elements, or thyristor and diode elements, in one pack-age; or the third may connect to the gate of a thyristor.1.3 Applicability and device functionThyristor SPDs are designed to conduct the surge currents necessary to provide overvoltage protection i

28、nelectrical circuits. The purpose of this document is to provide definitions and test methods for thyristor SPDthat are used for the protection of telecommunications systems. Overvoltage threats originate from lightningand ac power lines. These threats appear in the system through induction or direc

29、t contact. The waveformsthat are used in the tests are chosen to allow confirmation of manufacturers data.1The numbers in brackets correspond to those publications listed in the bibliography, Annex B.IEEEStd C62.37-1996 IEEE STANDARD TEST SPECIFICATION FOR 2Other types of thyristors may exhibit simi

30、lar characteristics. If they are used as thyristor SPDs, their surgesuppression capabilities may be characterized according to this specification.The thyristor SPDs exhibit a relatively high impedance in the off-state condition at normal system operatingvoltages before and after the surge. During th

31、e surge of sufficient voltage and current, the device will switchto a low-impedance (on-state) condition. After the surge has passed, the device is expected to recover to ahigh-impedance (off-state) condition. Consideration should be given to service conditions, temperatures, anddevice mounting when

32、 applying these parameters as variations may occur.2. Definitions of rated and other parameters2.1 Rated parameter valuesFor the purpose of this standard, the values of rated parameters are established by the manufacturer,according to statistical acceptance criteria as indicated in 4.2.2.2 Definitio

33、nsThe following apply specifically to thyristor SPDs and do not necessarily cover other devices. If the voltam-pere characteristics are asymmetrical, then the parameters shall be defined for each polarity.The relation between some common terms on some typical device V-I graphs are illustrated in Fig

34、ures 17.The characteristics of devices in the breakdown region can be complex and difficult to measure. All thepoints shown on the graphs may not be apparent on the actual device characteristic, and there maybe additional inflection points not shown. Conceptually, all of the points will exist for ev
