Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, to help understanding content of the present utility model.

As shown in Figure 1, a kind of escalator comprehensive detector connection terminal, is connected in the power line of escalator.For the escalator of direct triangle start, the the first power incoming end U1/V1/W1 comprising a three-phase is connected motor to the output of motor power transmitting contact device with the first power exit MU1/MV1/MW1 of a three-phase for connecting, and described first power incoming end U1/V1/W1 is connected with described first power exit MU1/MV1/MW1 circuit.The first switches set K1 is provided with between described first power incoming end U1/V1/W1 and described first power exit MU1/MV1/MW1.

Also comprise a zero line incoming end PE, the connection wire that three nodes between described first power incoming end U1/V1/W1 and described first switches set K1 draw wire and described zero line incoming end forms lambda line port IN, for connecting the incoming end of escalator comprehensive detector; Three nodes between described first switches set K1 and described first power exit MU1/MV1/MW1 and the connection wire of described zero line incoming end PE form outlet port OUT, for connecting the exit of escalator comprehensive detector.Wire between described outlet port and described first power exit is provided with the 3rd switches set.

For the escalator of direct triangle start, the first switches set K1 and the 3rd switches set K3 can select air switch.Escalator normally run do not detect time, the first switches set K1 close, the 3rd switches set K3 disconnect, the power system of escalator is normally run.When needing to carry out the detection of hypervelocity and non-operating reversed defencive function to this escalator; disconnect the first switches set K1; lambda line port IN, outlet port OUT connect incoming end and the exit of escalator comprehensive detector respectively; conjunction the 3rd switches set K3 is opened and closed after connection; such escalator comprehensive detector is access in elevator power system, thus detects elevator.After detection, disconnect the 3rd switches set K3, lambda line port IN, outlet port OUT, closed first switches set K1, circuit restPoses.Patch or take out stitches and determine whether access escalator comprehensive detector when noting be used in detection, simple to operate, not easily make mistakes.

Please refer to Fig. 2, for the escalator of direct triangle start, the first switches set K1 and the 3rd switches set K3 can select contactor.Control the closed of the first switches set K1 and the 3rd switches set K3 with switch SA1 or disconnect, after having detected, then restPosing, simple to operate, not easily make mistakes.

For the escalator of star triangle start, the second power incoming end U2/V2/W2 that this connection terminal also comprises a three-phase is connected motor to the output of motor power transmitting contact device with the second power exit MU2/MV2/MW2 of a three-phase for connecting.Described second power incoming end U2/V2/W2 is connected with described second power exit MU2/MV2/MW2 circuit, between described second power incoming end U2/V2/W2 and described second power exit MU2/MV2/MW2, be provided with second switch group K2.
