Fig. 2 is the user mode reference diagram of the utility model high voltage isolator divide-shut brake monitoring device.
Embodiment
Like Fig. 1, shown in Figure 2; High voltage isolator divide-shut brake monitoring device is made up of control circuit; Said this control circuit is made up of radiating circuit and receiving circuit; Said radiating circuit is made up of start button SB1, auxiliary relay KM, stop button SB2, infrared induction reflector successively, and said receiving circuit is made up of separating brake position signal circuit and the parallel connection of closing position signal circuit, and said circuit is by DC power supply.
The contact KM-1 of said auxiliary relay, KM-3 are normal opened contact; The contact KM-2 of said auxiliary relay KM, KM-4 are normal opened contact; After start button SB1 starts; The contact KM-1 of auxiliary relay KM, KM-3 closed communicating, the contact KM-2 of auxiliary relay KM, KM-4 closed communicating, the infrared induction reflector transmits.
Said separating brake position signal circuit is made up of intermediate relay ZJ, green light successively; Said closing position signal circuit is in series by intermediate relay ZJ, stop button SB2, red light, infrared reception inducing receiver successively, and the normally closed contact ZJ-2 of said green light, intermediate relay ZJ, ZJ-4 are communicated to zero line.
Said infrared induction reflector 2 and infrared reception inducing receiver 3 are installed on the rotation position of 1 time end link 21 of isolating switch porcelain vase respectively; When combined floodgate puts in place; Reflector 2 is located along the same line with receiver 3, and the infrared ray that receiver 3 is received reflector 2 promptly sends switching signal, during separating brake; Infrared induction reflector 2 staggers with infrared reception inducing receiver 3, and receiver 3 does not receive infrared ray and promptly sends sub-gate signal
During use, the following end link 21 rotation positions installation of porcelain vase is considered in the concrete installation site of intelligent supervisory device, and the position that had so both guaranteed to follow the tracks of disconnecting link 4 guarantees to keep enough safe distances with live part simultaneously.After 21 rotations of isolating switch mechanical linkage put in place, when receiver 3 received laser signal, the resistance at its two ends of diode in the device was very little, i.e. conducting, and inner sensitive switch S is closed, the ZJ actuating of relay, normal opened contact is uploaded the closing position of isolating switch.During mechanical linkage 21 change positions, when receiver did not receive infrared signal, the resistance at its two ends was very big, promptly opens circuit when the isolating switch separating brake, and inner sensitive switch S breaks off, and the ZJ relay normally closed contact is uploaded the position of isolating switch separating brake.Device inspection loop: intelligent supervisory device design review (check) (DR) loop, for guaranteeing the normal operation of device, relay control is adopted in site inspection; But the situation of operations staff's regular check device; Method is pressed start button SB1, voltage relay KM action, and its contact is connected reflector; After inspection finishes, press stop button SB2 device and recover normal.This monitoring device adopts the 6V DC power supply, therefore, and must be from 220V AC power rectification step-down.The contact that utilizes intermediate relay ZJ is as the on-the-spot divide-shut brake position signalling of disconnecting link.And be connected to intelligent control box with cable through the contact of auxiliary relay, and utilize optical fiber to be sent to station level after the switching signal through Ethernet interface, reach the purpose of record, analysis and judgement.
