Description
Technical field
The utility model relates to a kind of aggregate erection structure of thermal relay, specifically, relates to the main circuit of thermal relay and A.C. contactor, the plug-in type aggregate erection structure between the auxiliary circuit.
Background technology
The major function of thermal relay is exactly the phase failure and the overload protection of realizing circuit or motor; generally be used in combination with A.C. contactor; its circuit theory as shown in Figure 1; being about to thermal relay main circuit 1,3,5 is connected in the main circuit 2,4,6 of A.C. contactor; auxiliary circuit 95,96 is connected to respectively among the control circuit A2,14 of A.C. contactor; when the phase failure and overload appear in circuit and motor; the thermal relay action; auxiliary circuit 95,96 disconnects; AC-control coil A1, A2 are discharged; disconnect main circuit, circuit and motor are protected.
Alternating current motor with Fig. 1 is an example, and before motor M did not put into operation, the control coil A1/A2 of contactor KM is energize not, and main circuit contact 1/2,3/4,5/6,13/14 is in off-state, and the auxiliary contact 95/96 of thermal relay FR is in closure state.Console switch SB2, A1/A2 energized, 1/2,3/4,5/6,13/14 closure, the operation of M energized, FR flows through the operating current of M, and after SB2 discharged, M entered operate as normal.When the phase failure or overload appearred in main circuit or M, FR moved because of the electric current that flows through changes, and auxiliary contact 95/96 disconnects, and control coil A1/A2 is cut off, and the contactor outage discharges, and the KM main circuit disconnects, and motor M is cut off the power supply, and shuts down.
Circuit between thermal relay and the A.C. contactor connects and divides stand alone type installation and plug-in type aggregate erection.Fig. 2 is the connection diagram that stand alone type is installed.As shown in the figure, the input terminal of thermal relay 21 inserts in the side terminal of an independent pedestal 23 that mates, and the opposite side of pedestal terminal 23 connects with A.C. contactor 22 respective terminal with lead 24 again.This kind connected mode because the connection between thermal relay 21 and the A.C. contactor 22 must possess transition lead 24 and a separate connection pedestal 23, causes syndeton complexity, material wasteful, and volume is big, the poor reliability that connects.
For this reason, adopted another kind of plug-in type aggregate erection mode both at home and abroad, the signal of this kind installation as shown in Figure 3, the terminal 311,313,315 of thermal relay 31 directly inserts the corresponding terminal 322,324,326 of A.C. contactor 32, does not need the transition lead between the two.Thermal relay main circuit 1,3,5 in terminal 311,313,315 corresponding diagram 1 wherein, the main circuit 2,4,6 of the A.C. contactor in terminal 322,324,326 corresponding diagram 1.
Above-mentioned plug-in type aggregate erection mode, the complex structure, the material that have seemingly solved free-standing mounting means existence outwardly are wasteful, and volume is big, the problem of connection reliability difference, but the connecting circuit between thermal relay and the A.C. contactor has two kinds of main circuit, auxiliary circuits, present plug-in type aggregate erection only is applied to the connection between the main circuit of thermal relay and A.C. contactor, and the auxiliary circuit part still adopts external wiring way, be incomplete aggregate erection, therefore reality does not solve a series of problems that free-standing mounting means causes.
