Definitions
- the invention relates to high-intensity three-phase switchgear, with or without neutral, with polar compartments connected in parallel.
- the document EP 0 320 412 describes a high-intensity three-phase switchgear, in this case a circuit breaker, comprising two adjacent pole compartments per pole, and two adjacent polar compartments for the neutral.
- Each polar compartment has two separable contacts each connected to a contact pad.
- the polar compartments of the same phase are paired by electrically connecting two to two contact pads via a connection strip.
- Each pair of twisted poles thus constitutes a current loop formed by the two connection strips and conductors of the two pole compartments.
- Each phase is connected at its connection bars to a busbar.
- the device turns out difficult to implement when the phase imbalance becomes significant or when the size of the device increases.
- the crossing of conductors in the same magnetic circuit if it does not pose a problem for currents of average intensity, of the order of 630A, can no longer be applied for very high intensity switchgear, above 4000A in particular, for reasons obvious size. It is precisely on very high intensity devices that the effect of mutual induced electromotive forces between branches of the circuit internal electrical wiring becomes critical.
- the teaching of the document FR 2 063 078 therefore does not solve the specific problem posed by the effect of proximity between phases described above.
- Another method to stabilize the distribution of current between the two branches corresponding to two twinned poles of the same phase of a power circuit breaker low voltage would consist in placing the two poles of each phase in a non- contiguous, for example so that the two poles of each phase are separated from each other by one of the poles of each of the other two phases. If we number from 1 to 6 the six pole compartments from one side to the other of the circuit breaker, we would thus have: poles 1 and 4 for a first phase, poles 2 and 5 for a second, and poles 3 and 6 for the third phase. But such a provision generates a large footprint at the busbars of the different phases and bridges between poles of the same phase.
- the invention therefore aims to improve or even optimize the distribution of electric current and temperatures between the twin poles making up the phases of a switchgear three-phase break with contiguous twin poles, limiting the additional cost induced by provisions adopted as well as the increase in the size of the apparatus.
- bypasses are part of the apparatus, eliminates the influence parts of the circuit located outside the apparatus, in particular the influence of power busbar.
- the current loops of each phase formed by the conductors of the two polar compartments and the jumps upstream and downstream, are defined from the design of the equipment, and do not depend on the assembly on site. It is therefore possible to calibrate the magnetic circuit judiciously, so as to obtain the desired compensation for feeding conditions data. The compensation obtained is then independent of the composition or the arrangement of the upstream and downstream circuits, and in particular the arrangement of the sets of bars.
- the magnetic circuit of compensation is part of a current transformer further comprising a secondary supply winding of an electronic circuit of the apparatus.
- the switching devices are often fitted with at least one magnetic circuit supply disposed on each of the polar circuits. We then use, for the compensation, one of the existing magnetic supply circuits, and we just not to mount the magnetic supply circuit of the adjacent polar compartment of the same phase. The desired effect is then obtained with a lower cost per compared to the unit cost of a pole.
- the air gap is said to be partial when it is non-zero over part of the section of the shunt, and zero on the remaining part of the section.
- This type of circuit described for example in the document EP 0 704 867, conventionally offers the advantage of shunting the core ensuring the secondary circuit supply, when the primary current exceeds a certain threshold value.
- This type of magnetic circuit here also makes it possible to separate the two supply and compensation functions, fulfilled by the magnetic circuit. We can indeed dimension relatively independently of one another, of a the core intended for the power supply function of the electronic circuit, and on the other hand the shunt ensuring the compensation and clipping function beyond the threshold value.
- the current transformer is located inside said polar compartment. We use then the location usually dedicated to the supply current transformer.
- the current transformer is located outside of said polar compartment. This layout provides more room to house the magnetic circuit. It also allows to prevent the heating of the magnetic circuit caused by iron losses does not heat the corresponding inner polar compartment.
- the magnetic compensation circuit is dimensioned in such a way so that when the switchgear is supplied in three-phase mode balanced at its voltage rated current, and crossed by its rated current at its rated frequency, each circuit magnetic compensation generates in the inner polar compartment a impedance such that the current passing through the inner pole of each lateral phase is less than or equal to the current flowing through the other pole of the same phase.
- Strict equality between the effective values of the currents crossing the two branches of a lateral phase allows to obtain the balance between the energies dissipated in the two compartments of the same phase.
- heat dissipation is potentially more important for the outer poles lateral phases. In this case, overcompensation allows the most large share of current in the easiest compartment to cool.
- the bridges are secured to the housing.
- the equipment is then delivered on site with its bridges mounted.
- the bridges are fixed at the outside of the polar compartments.
- connection circuits between the connection pads and the contact including racking-in pliers.
- a three-phase hexapolar circuit breaker 10 includes a insulating housing formed by assembling a rear base 12, an intermediate block 14 with open bottoms and a front face 16, which delimit a rear compartment and an anterior compartment, on either side of an anterior partition 18 of the block intermediate 14.
- a control mechanism 20 of circuit breaker 10 which acts on a switching shaft 22 common to the assembly of the circuit breaker poles. This mechanism 20 is attached to the anterior partition 18 of the intermediate block 14.
- the rear compartment is itself subdivided into six elementary polar compartments 24, 26, 28, 30, 32, 34 by partitions dividers 25, 27, 29, 31, 33.
- the pole compartments are aligned side by side and thus form three adjacent pairs, each pair corresponding to a phase of the circuit breaker.
- the partitions 25, 29 and 33, which each separate the two compartments poles of the same phases, are provided with a communication orifice 36, described in detail in document FR 2 778 788. This orifice 36 is intended to improve the distribution of the breaking energy during the separation of the contacts.
- Partitions 27 and 31 are waterproof.
- the phase comprising the compartments polar 28, 30 will be called the middle phase, and the other two phases, which frame the median phase, will be called lateral.
- One of the lateral phases includes the polar compartment 26 said interior, adjoining polar compartment 28 of the phase median and the polar compartment 24 said exterior, while the other lateral phase has the so-called inner polar compartment 32, adjoining the polar compartment 30 of the middle phase, and the pole 34 said outside.
- Each pole includes a movable contact member 40, a fixed contact member 42, and an arc extinguishing chamber 44 provided with separators, as well as the compartment corresponding polar which at least partially houses these elements.
- the organ of fixed contact 42 includes a contact pad 46 of conductive material, the occurrence of copper, crossing the rear base 12 of the housing, and a pellet of contact 48.
- the movable contact member 40 is provided with a plurality of contact fingers 50 arranged side by side and pivotally mounted on a first transverse axis 52 of a support cage 54. The heel of each finger 50 is connected to a second range of contact 56 passing through the base 12, via a braid 58 made of material driver.
- the contact pads 46, 56 are intended to be connected to the network upstream and downstream, for example through a busbar.
- the end of the cage 54 located near the second contact pad 56 is fitted with a pin housed in a bearing integral with the insulating housing, so as to allow the pivoting of the cage 54 between a open position and closed position of the pole around a geometric axis 59 shown in Figure 3.
- a contact pressure spring device 60 is disposed in a notch in the cage 56 and urges the contact fingers 50 to pivot about of the first axis 52 in the direction of the contact 48.
- Each contact finger 50 has a contact pad 62 which, in the position shown in FIG. 3, is in contact with the single pad 48 disposed on the fixed contact member 42.
- the cage 54 is coupled to the switching shaft 22 by means of a connecting rod transmission 64 so that the rotation of the shaft 22 induces a pivoting of the cage 54 around the axis 59.
- FIG 2 In Figure 2 is shown a bridge 70 of conductive material which connects electrically the fixed contact members 42 of the two adjacent poles 24, 26 forming one of the lateral phases.
- a jumper 72 electrically connects the organs of movable contacts 40 of the two adjacent poles 24, 26.
- the other two phases are also provided with bypasses identical to bypasses 70, 72, but these bypasses have not shown in Figure 2, to allow the posterior part to be viewed contact pads 46, 56.
- the bridges 70, 72 allow the twinning of the adjacent poles connected in parallel, and constitute a current loop with the conductors located in the twin pole compartments.
- each of the inner poles 26, 32 of the phases side is fitted with a current transformer 80, intended to supply a circuit circuit breaker electronics.
- the supply current transformer 80 comprises, in a manner known per se, a magnetic circuit 82 composed by a stack of transformer sheets, forming a magnetic circuit around the conductor constituting the contact pad 56 of the movable contact member 40, and a winding 84 constituting a secondary supply winding of the electronic circuit of the circuit breaker.
- the compensation transformer 80 is of the magnetic shunt type with partial or total air gap, as described in document EP 0 704 867 A.
- the circuit magnetic comprises a main circuit 83 surrounding the primary conductor constituted by contact pad 56.
- a portion of the main magnetic circuit 83 constitutes a magnetic core 85 of the secondary winding 84.
- the magnetic circuit 82 further includes a magnetic shunt 86 bypassed on the core 85.
- This shunt magnetic has an air gap 87, located between one end of the shunt 86 and a part of the main magnetic circuit, which connects an area close to the primary conductor and the core 85 of secondary winding 84.
- the section of magnetic shunt 86 to proximity to the air gap, is greater than the section of the magnetic circuit at the location of the core 85 of secondary winding 84.
- the main magnetic circuit 83, the core 85 and the shunt 86 form a single piece, constituted by stacked sheets or by other magnetic materials.
- the two outer poles of the lateral phases are, for their part, devoid of supply current transformers, as shown in figure 4.
- Each of the two poles 28, 30 of the middle phase comprises a transformer supply current 80a identical to transformers 80, with one circuit magnetic 82a and a secondary winding 84a.
- At least one supply current transformer 80, 80a of the circuit electronic by phase is made necessary to ensure the functioning of circuit breaker electronics in all configurations of use, and in particular when only one of the three phases is supplied.
- each of the polar compartments is provided with a measuring toroid 88 called of Rogowsky surrounding the contact pad, delivering a low power signal proportional to the current flowing through the contact range.
- FIG. 6 schematically represents the electrical circuit formed by the three phases of the circuit breaker, connected to an upstream busbar 90 and to a downstream busbar 92.
- the bridges 70, 72 are connected between the upstream busbar and the set of bars downstream of the phase.
- ⁇ I then represents a loop current, which is zero when the currents are balanced.
- the two branches of the current loop are identical, from made of the presence of a current transformer 80a in each branch, and are subject to relatively balanced electromagnetic influences generated by the lateral phases. Consequently, the current is distributed relatively balanced between the two branches of the middle phase.
- the circuit branch comprising the compartment inner pole (26, respectively 32) is provided with a magnetic circuit 82 constituted by the supply current transformer 80, which has no equivalent in the branch comprising the external compartment (24, resp. 34).
- a magnetic circuit 82 constituted by the supply current transformer 80, which has no equivalent in the branch comprising the external compartment (24, resp. 34).
- This imbalance is due to the interactions between phases, which are reflected at the level of each branch of the current circuit by an inductor of different value.
- the current passing through the inner pole is always higher than the current crossing the corresponding outer pole.
- transformers 80 are ideally identical to 80a transformers of the middle phase, which do not have the rebalancing function. But it is also possible to provide specific transformers 80, differing transformers 80a by their size or their constitution.
- the structure of the magnetic circuit 82 with an air gap shunt 87 offers the advantage of allow to separately size the core 85 and the shunt 86 for their function clean.
- the air gap 87 of the shunt 86 in fact causes non-linear behavior of the transformer: at low primary current level, only a very small portion of the flux magnetic can pass through the shunt 86 and cross the air gap 87; almost all of flux then passes through the magnetic core 85.
- the primary current I increases, the proportion of magnetic flux that can pass through shunt 87 increases and the proportion of flux passing through the core 85 decreases.
- the magnetic flux passing through the air gap increases very rapidly when the magnetic induction produced by the primary current flowing in the conductor exceeds a certain threshold, which is determined by the size and shape of the air gap.
- the air gap of the shunt can be total or partial. In the latter case, there is one more parameter for optimization of the non-linear behavior of the shunt, namely the section of the part of the shunt with zero air gap.
- the transformer compensation current 80 on the rear side of the rear base of the housing, outside of the polar compartment, the main thing being that it is inside the current loop defined by the two bridges, on the internal branch of the lateral phases. This provision prevents the presence of the current transformer causing a pole heating. We can then do without specific constructive arrangements limiting the heating of the transformer itself.
- each pole is provided of a supply current transformer.
- a magnetic compensation circuit specific is then added to the internal branches of the phase current loops side.
- FIG. 8 shows an electrical diagram of an electrical switchgear according to a second embodiment of the invention.
- the reference signs used are identical to those of the first embodiment, for identical parts.
- the apparatus comprises a chassis in which is able to slide a housing of circuit breaker, between a plugged-in position and a withdrawn position.
- the circuit breaker is composed of polar compartments similar to those illustrated in the first mode of realization of the invention.
- the contact pads 46, 56 of each pole are connected to connection pads 100 supported by a plate 102 forming the bottom of the chassis, by means of racking-in pliers 104.
- a pliers is shown single plug-in per contact pad, but a plurality can also be provided racking pliers by contact area, as described for example in the document EP 0 926 793.
- connection areas 100 are linked in pairs by bridges 106, 108 whose function is identical to that of the bridges 70, 72 of the first embodiment. So are formed by current loops which group, for each phase, the bridges 106, 108, the connection pads 100, the racking-in pliers 102, and the twin pole contacts.
- all the compartments breaker poles are fitted with a supply current transformer 80a.
- a magnetic compensation circuit 110 is also arranged in the internal branch. of each lateral phase. This magnetic circuit 110 has an inductance making it possible to compensate for the imbalance due to the interaction between phases.
- This variant has the advantage of allowing balancing on a loop of larger dimension, including racking-in pliers 107 and at least partially the connection pads 100. It also makes it possible to arrange the circuit balancing magnet 110 outside the case of the circuit breaker 10, in a place where it has little influence on the internal temperature of the polar compartments. On the other hand, it requires additional magnetic circuits compared to the first mode of production. In addition, it does not allow complete manufacturing in the factory.
- the circuits magnetic compensation can be arranged either outside the chassis, as indicated in FIG. 7, either inside, on the face of the plate 102 facing the circuit breaker 10, or even between the contact pads and the clamps.
- the housing made of insulating material can consist of two parts, each corresponding to a case of a circuit breaker three-phase to one pole per phase, these two parts being assembled to each other as described in document EP 0 320 412.
- the invention applies as well to a three-phase apparatus with neutral as to a three-phase switchgear without neutral.
- the neutral can have one or two compartments polar, located next to one of the lateral phases. Its influence on the distribution of steady-state currents is low and does not require compensation particular.
- the switchgear can be a circuit breaker, a switch, with or without the sectioning and, in general, any switchgear at very high rated intensity.
- Measuring toroids, magnetic supply and / or compensation circuits can be arranged either on the side of the movable contact member or on the side of the fixed contact member.
- the bottom line is that the magnetic circuits used to compensation are inside the current loop delimited by the bridges, on the internal branch of the lateral phases.
- the measurement toroids, and the circuits magnetic feed and / or compensation can be arranged interchangeably on the source side or on the load side.
- the magnetic compensation circuits it is possible to size the magnetic compensation circuits to obtain a balancing of the currents i 1 and i 2 for an effective value of the current I corresponding to the rated current (within the meaning of standard IEC 947-2), ie the rating of the circuit breaker. It is also possible to provide partial compensation, in particular if the aim is essentially to homogenize the temperatures inside the polar compartments. Indeed, it has been indicated that the magnetic circuit is itself a heat source which, if the circuit is inside the compartment or around the contact area, influences by thermal conduction and / or thermal radiation, on the temperature inside the compartment.
- the magnetic circuit dissipates little heat or if it is arranged outside the polar compartments, it is also possible, on the contrary, to provide for overcompensation, by dimensioning the magnetic circuit in such a way that the effective value of the current intensity in the inner pole is less than the rms value of the intensity in the outer pole.
- the cooling of the outer polar compartments of the lateral phases is easier because on one side, they are not exposed to the heat of an adjacent compartment.
- the optimum for temperature balancing can therefore correspond to a higher current in the outer pole of the lateral phases.
- the magnetic circuit is not necessarily of the magnetic shunt type with total or partial air gap.
