In figure: QF1, QF2 are air switch; KA is auxiliary reclay; HL1, HL2, HL3, HL4 are pilot lamp; 5-PS Switching Power Supply; 8-auxiliary reclay mounting seat; 9-connecting terminal block; 10-guide rail.
Embodiment
Below in conjunction with accompanying drawing, apparatus of the present invention are further described.
As shown in Figure 1, the easy verifying attachment of auxiliary reclay of the present invention comprises the mounting bracket of the structure that is square, mounting bracket is provided with connecting terminal block 9, auxiliary reclay mounting seat 8, pilot lamp (this example is four pilot lamp HL1, HL2, HL3, HL4) that quantity is identical with the contact logarithm of auxiliary reclay and PS Switching Power Supply 5, the solenoid of auxiliary reclay KA is drawn respectively by wire with number docking point and is received on connecting terminal block 9, and every docking point is connected a pilot lamp.As shown in Figure 3, be connected with the PS Switching Power Supply 5 that alternating current 220V can be converted to direct current 24V after four pilot lamp are connected in parallel, and access air switch QF2, to control the break-make of pilot lamp loop.As shown in Figure 2, the connection terminal being received auxiliary reclay KA solenoid with the supply unit wire of voltage output function by the connecting terminals of connecting terminal block 9 provides detection power supply for auxiliary reclay, and read voltage value, and on link circuit, be connected in series air switch QF1, to control the break-make of measure loop
Auxiliary reclay KA is fixed in the mounting seat 8 of coupling, and mounting seat 8, air switch QF1, air switch QF2 and connecting terminal block 9 hang on guide rail 10, and guide rail 10 is fixed on the base plate of device.
The present invention directly plugs by auxiliary reclay mounting seat 8 when not changing wiring and changes auxiliary reclay, additional supply unit provides inspection power supply to verified auxiliary reclay KA, supply unit can regulate supply voltage on demand, directly can read magnitude of voltage simultaneously, every docking point of auxiliary reclay KA is accessed a pilot lamp respectively, when middle relay K A action rear indicator light HL1, HL2, HL3 and HL4 loop is connected, pilot lamp is lighted, and inspection loop controls break-make by air switch QF1; Pilot lamp HL1, HL2, HL3 and HL4 provide power supply by the PS Switching Power Supply 5 that alternating current 220V is converted to direct current 24V by pilot lamp, and control break-make by air switch QF2.
The mounting seat 8 of auxiliary reclay of the present invention can be changed at any time according to different auxiliary reclay models.
The present invention is by using the base matched with institute's inspection auxiliary reclay model, the solenoid of relay and contact are drawn out on connection terminal, simultaneously by relay tip series connection access pilot lamp loop, then use adjustable source to solenoid making alive, read action and the return voltage of relay by voltage instrument, then observed the connection situation of relay tip by pilot lamp easily and intuitively.Relay only need be inserted on base by whole checking procedure, and then regulating power source voltage can complete inspection work.
