Definitions

  • the invention relates to a connection assembly comprising a first connector, fixed, integral with the housing of an electronic trip device of a circuit breaker for protection of a polyphase electrical network with neutral, and a second movable connector, the first and second connectors comprising additional terminals intended to be connected when the connectors are plugged in, the terminals of a connector being separated by a predetermined pitch, the fixed connector comprising phase and neutral terminals connected respectively to phase and neutral inputs of the trip device, and the mobile connector comprising phase and neutral terminals respectively connected to phase and neutral current transformers.
  • the invention aims to reduce the cost of this connection.
  • the fixed connector comprises two neutral terminals, arranged on either side of a number p of phase terminals, the movable connector comprising a number p + 1 of terminals .
  • a three-phase electrical network (L1, L2, L3) with neutral (N) is protected by a circuit breaker having a set of contacts 1 controlled by an electronic trip unit 2, via a relay control 3.
  • the circuit breaker comprises current transformers 4, respectively 4a, 4b, 4c and 4n, intended to supply respectively to phase inputs Ea, Eb, Ec and neutral of trigger 2 a measurement of the current respectively in the lines L1, L2, L3 and N of the network.
  • the invention relates to the connection assembly between the current transformers 4 and the regulator 2.
  • the circuit breaker conventionally comprises a number p of poles associated with the p phases of the network and a pole associated with neutral, that is to say in the case of a three-phase network with neutral, four poles.
  • the pole associated with neutral can be placed to the left or right of the poles of the circuit breaker associated with the phases.
  • the trip unit has inputs associated respectively with each of the phases and with neutral.
  • the connection between the current transformers 4, arranged in the corresponding poles of the circuit breaker, and the associated inputs of the trip device must take these variants into account. Until now, this has been done using different connectors for each variant.
  • connection assembly As shown in FIGS. 2 to 4, the connection assembly according to the invention consists of a fixed connector 5, standard, mounted on one face of the trip unit housing 2 and by a movable connector 6 serving as an interface between the transformers of current 4 and trigger 2.
  • the fixed connector 5 has terminals 7 separated by a predetermined pitch d.
  • the part of the fixed connector 5 intended to be connected to the current transformers comprises three adjacent phase terminals, 7a, 7b, 7c, connected to the phase inputs Ea, Eb, Ec, of the trip device. It further comprises two neutral terminals, 7n1 and 7n2, arranged on either side of the phase terminals and both connected to the neutral inputs of the trip unit.
  • the movable connector 3 has ( Figures 3 and 4) four terminals 8, separated by the pitch d and complementary to the terminals 7. These terminals are respectively connected to the current transformers 4a, 4b, 4d and 4n. If the neutral pole of the circuit breaker is located on the left with respect to the poles associated with the phases, to simplify the wiring as much as possible, the current transformer 4n associated with the neutral pole is connected to the leftmost terminal of the movable connector, 8n1 on the Figure 3.
  • the current transformers 4a, 4b, 4c are respectively connected to the adjacent terminals 8a1, 8b1 and 8c1, from left to right, in Figure 3.
  • the connectors 6 and 5 are then connected, the terminals 8n1, 8a1, 8b1 and 8c1 connecting respectively with terminals 7n1, 7a, 7b and 7c.
  • the axis 9 shown in Figures 2 and 3 symbolizes the fact that the terminals 7n1 and 8n1 of the connectors 5 and 6 are associated.
  • the current transformer 4n is connected to the rightmost terminals of the movable connector, 8n2 in FIG. 4
  • the current transformers 4a, 4b and 4c are connected to the adjacent terminals, respectively 8a2, 8b2, 8c2, from left to right in FIG. 4.
  • the terminals 8a2, 8b2, 8c2 and 8n2. mate with terminals 7a, 7b, 7c and 7n2 respectively.
  • the axis 10 shown in FIGS. 2 and 4 illustrates the fact that the terminal 8n2 of the connector 6 is associated with the neutral terminal 7n2 of the connector 5.
  • the phase inputs Ea, Eb, Ec and neutral En are, as before, automatically connected to the corresponding current transformers 4a, 4b, 4c and 4n, respectively.
  • the neutral terminal can then be located either on the left (8n1, figure 3) or on the right (8n 2, figure 4) and by a simple lateral offset, from the pitch of the mobile connector, the neutral terminal is aligned (with 9 or 10) with one of the neutral terminals of the fixed connector when the associated phase terminals are coupled.
  • connection assembly is standardized, as regards both the fixed connector and the mobile connector. Differentiation between circuit breakers with the neutral pole on the right or on the left can be done very late, at the distributor level rather than at the production center.
  • the additional terminals of the fixed connector 5 shown in FIG. 2 are not used for the connection between the current sensors and the trip device. They are used to connect the trip unit to certain auxiliary functions, such as a power supply or the trip control relay, for example.
