- the resistance of the first group is chosen for be able to permanently withstand a current of value at most equal to 1/35 of the maximum value of the short-circuit current of the line.
- the resistance of the second group is chosen for be able to permanently withstand a current of value equal to About 1/15 of the permanently supported current value by the resistance of the first group.
- the resistances of the first and second groups are consisting of an alternating stack of polymer disks loaded with carbon and metal discs good conductor of electricity.
- the stack is surrounded by a waterproof envelope filled with insulating gas.
- the initial value of the resistance of the first group is around 0.1 ⁇ .
- the initial value of the resistance of the second group is around 1.5 ⁇ .
- the resistance of the second group is provided with a rapid heating device controlled when the first group circuit breaker.
- the device is characterized in that the first threshold value is between two thirty-fifths and thirty-fifths of the maximum value (Icc) of the current line short circuit.
- the device is characterized in that the second threshold value is between one five hundredth and one thousandth of the maximum value (Icc) of the short-circuit current of the line.
- the reference LL 'denotes one of the two direct current line conductors; the device the invention may include two identical sets inserted respectively in series on each of the two conductors line. Only one of the sets is represented in the Fig. 1., in a dashed rectangle designated by the reference 1.
- Resistors R1 and R2 are made up of the same as described below.
- the resistor comprises a plurality of discs 13 in polymer charged with carbon with two metallized faces, separated by discs 14 made of metal which is a good conductor of electricity, preferably copper.
- Polymer and copper constitute a stack placed between two flanges metal end 11 and 12; the flanges are tight by insulating rods 15 threaded at their ends and fitted with nuts 16.
- On the flanges are welded conductors 18 and 19 used for the electrical connection with the line and with the circuit breaker.
- the whole constituting the resistance is protected by an envelope waterproof insulation not shown, filled with gas dielectric such as nitrogen.
- varistors 17 or resistances of low ohmic value
- the polymer resistance charged carbon have room temperature resistance of around a tenth of an ohm and at a temperature between 100 and 110 ° C, their resistance is suddenly multiplied by a factor of the order of 5000.
- resistance R1 The characteristics of resistance R1 are: following.
- Resistor R1 can support a permanent current inl equal to around 15% of In for a short-circuit current maximum Icc of 10,000A on line LL ', In designating the nominal value of the line current.
- the initial resistance of R1 is around 0.1 ohm, for a network voltage of 100 kV.
- Icc / in1 at least equal to 35.
- resistance R2 The characteristics of resistance R2 are: following.
- Resistor R2 can withstand a permanent current in2 equal to approximately 1% of In, i.e. 20 A if In is equal to 2,000 A.
- in2 will be equal to 40 A.
- resistors R1 and R2 More generally we choose resistors R1 and R2 so that the ratio in1 / in2 is close to 15.
- the initial resistance of R2 is around 1.5 ohm for a network voltage of 100 kV.
- the disks 13 of the resistor R1 have for example a section of 220 cm 2 ; the diques 13 of the resistance R2 will then have a section of 15 cm 2 .
- the operation of the device is as follows.
- circuit breakers D1 and D2 and the disconnector S are closed.
- the current flows through circuit breakers, whose ohmic value of the resistances of contact is weak compared to the resistance value R1 and R2.
- the current also passes through the disconnector S.
- the DD current detector gives to circuit breaker D1, on a exit 3, an opening order.
- resistance R1 will change in ohmic value by Joule effect more or less fast, for example in 15 milliseconds if the current of fault is 10,000 A, in 60 milliseconds if the current of default is 5,000 A.
- the sudden change in ohmic value of the resistance R1 causes a sudden decrease in current; this reduction is detected by the DD detector which, when the value of the current reached by lower value a first predetermined threshold, gives on an output 4, a opening order at circuit breaker D2.
- This threshold is by example between 2in1 and in1, between two thirty-fifths and one-thirty-fifth of the maximum value (Icc) of the line short-circuit current.
- the residual current is cut by the disconnector, upon detection by the DD detector for passing through a lower value of second predetermined threshold.
- This order is transmitted by a link 5.
- the aforementioned threshold is for example between in2 and 0.5 in2, approximately between one five hundredth and one thousandth of the maximum value (Icc) of the short-circuit current of the line.
- the resistance R2 is advantageously equipped with a rapid heating device C which is route from the opening of circuit breaker D1, either by an order emitted by the DD fault detector (3 'link), either by a command not shown linked to the movement of circuit breaker contacts D1.
- This heating device in rapidly heating resistance R2 to a temperature of 100 ° C approximately, accelerates the transition from resistance R2.
- the faultless interruption of the nominal current In, or of a current of value less than In is carried out according to the same process as that just described, but in controlling the opening of circuit breaker D1 directly, without involve the fault detector at this stage.
- Circuit breakers D1 and D2 are chosen to have a "opening time" of the order of 20 milliseconds; the disconnector has an opening time of a few seconds.
- the invention finds application in the equipment of high voltage direct current networks.
