Definitions

  • the invention relates to a connection assembly comprising a first connector, fixed, integral with the housing of an electronic trip device of a network protection circuit breaker polyphase electric with neutral, and a second mobile connector, the first and second connectors with additional terminals intended to connect when plug-in of connectors, the terminals of a connector being separated by a pitch predetermined, the fixed connector having connected phase and neutral terminals respectively to phase and neutral inputs of the release, and the movable connector having phase and neutral terminals respectively connected to transformers phase and neutral current.
  • the invention aims to reduce the cost of this connection.
  • the fixed connector comprises two terminals of neutral, 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 a trip unit electronic 2, via a control relay 3.
  • the circuit breaker includes current transformers 4, respectively 4a, 4b, 4c and 4n, intended to supply respectively at phase inputs Ea, Eb, Ec and neutral En of trigger 2 a measurement current respectively in lines L1, L2, L3 and N of the network.
  • the invention relates to the connection assembly between the current transformers 4 and the trigger 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, i.e. in the case of a three-phase network with neutral, four poles.
  • the pole associated with neutral can be arranged left or right of the circuit breaker poles associated with the phases.
  • the trigger has inputs associated with each phase and neutral respectively.
  • the connection between current transformers 4, arranged in the corresponding poles of the circuit breaker, and the associated entries of the trigger must take these variants into account. So far this has been achieved by means of different connectors for each variant.
  • connection assembly As shown in Figures 2 to 4, the connection assembly according to the invention consists by a fixed connector 5, standard, mounted on one face of the trigger housing 2 and by a movable connector 6 serving as an interface between the current transformers 4 and the trip device 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 transformers current has three adjacent phase terminals, 7a, 7b, 7c, connected to the inputs of phase Ea, Eb, Ec, of the trigger. It also has two neutral terminals, 7n1 and 7n2, arranged on either side of the phase terminals and both connected to the inputs of neutral of the trigger.
  • the movable connector 3 comprises ( Figures 3 and 4) four terminals 8, separated by the pitch d and complementary to terminals 7. These terminals are respectively connected to transformers current 4a, 4b, 4d and 4n. If the neutral pole of the circuit breaker is located on the left relative to the poles associated with the phases, to simplify the wiring as much as possible, the transformer current 4n associated with the neutral pole is connected to the leftmost terminal of the connector mobile, 8n1 in FIG. 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.
  • terminals 8n1, 8a1, 8b1 and 8c1 are connected respectively with terminals 7n1, 7a, 7b and 7c.
  • Axis 9 shown in Figures 2 and 3 symbolizes the fact that terminals 7n1 and 8n1 of connectors 5 and 6 are associated. So when connection of connectors, phase inputs Ea, Eb, Ec of the trip unit are automatically connected respectively to the corresponding current transformers and the neutral inputs En at the 4n current transformer.
  • the 4n current transformer is connected to the terminals rightmost 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 Figure 4.
  • terminals 8a2, 8b2, 8c2 and 8n2 mate with terminals 7a, 7b, 7c and 7n2 respectively.
  • Axis 10 represented on the Figures 2 and 4 illustrates the fact that the terminal 8n2 of the connector 6 is associated with the terminal of neutral 7n2 of connector 5.
  • the inputs of phase 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 left (8n1, figure 3), or right (8n 2, figure 4) and by a simple lateral offset, the pitch of the movable 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, both with regard to the fixed connector as the movable connector.
  • the differentiation between the circuit breakers having the pole neutral 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 Figure 2 are not used for connection between the current sensors and the release. They are used for the connection of the release to certain auxiliary functions, such as a power supply or the relay trigger control, for example.
