(2), the hot and cold subsequent use conversion operations light detection method of switch dolly:
Switch dolly cold (testing position), stand-by heat (run location) conversion operations light detect by 1 " switch dolly light detects baffle plate (Fig. 4) " and 1 " U type diplopore light detection and location devices (Fig. 3) " and constitute light detection front device.Be fixed on separating brake on the switch dolly, combined floodgate light detect baffle plate with switch dolly moving contact close, divide do before and after translation, be fixed on U type diplopore light detection and location device on the switch switch cabinet and adopt left and right sides independent light to detect to make up again method for position is carried out switch dolly mechanical property discriminatory analysis.For specifying the process of switch dolly motion detection method; Select carefully to state the switch dolly is changeed stand-by heat by cold standby grid switching operation process; The switch dolly is moved to standard stand-by heat position 4.1 by standard cold standby position 4.5; The switch dolly is accomplished " three phases " stroke; Row's light detects light and detects upward row interval switching value 0101 of baffle plate (Fig. 4) on the U type diplopore light detection and location device ... The transformation period of 0101 number, position and each switching value, row's master switch amount is counted the percentage that ratio promptly is switch dolly displacement on detected switching value number and the light detection baffle plate, row interval switching value 0101 in the completion ... 0101 omnidistance number detects; Under arrange light and detect light and detect baffle interval switching value 101; Confirm that then the switch dolly has moved to the stand-by heat position, the flash ranging bright dipping detects on the baffle plate and arranges 0101 ... 0101 omnidistance switching value number changes with the corresponding time of each position and changes the correspondence position mechanical property of compute switch dolly.Light detector switch dolly moves in different phase, and switch dolly translational speed is different; Appearance light detector switch amount does not change or corresponding time of each position changes greater than each stage criterion traveling time variation, judges switch dolly appearance " jam ", and light detector switch dolly moved in the phase one; Wall controller then CS dolly is retracted into the cold standby position; Light detector switch dolly moves in subordinate phase, and wall controller then CS dolly moves the thermotropism spare space once more, occurs once more " jam "; Wall controller then force switch dolly is retracted into cold standby position (the slowest step velocity; Big starting current), light detector switch dolly moved in the phase III, and wall controller then CS dolly is claimed the thermotropism spare space; Occur once more " jam "; The wall controller is the control of shutdown switch dolly then, and when the switch dolly changes moving direction (electronic), the wall controller carries out detected switching value number automatically and successively decreases or increase progressively; Confirm the percentage of switch dolly displacement, on the basis of program grid switching operation, realize " intelligence " operation.
(3), knife-like switch separating brake, closing operation light detection method:
Knife-like switch separating brake, closing operation light detect respectively and at each moving contact insulation porcelain axis of a cylinder of every phase " knife-like switch light detects baffle plate (Fig. 7) " are installed; " isolating switch, knife-like switch operating mechanism main shaft light detect baffle plate (Fig. 6) (then every 1 isolating switch, the knife-like switch operating mechanism main shaft light detection baffle plate installed mutually of three-phase independence operating mechanism) " is installed at isolating switch, knife-like switch operating mechanism main shaft; Corresponding light detects baffle position " U type single hole light detection and location devices (Fig. 2) " is installed one to one on knife-like switch operating mechanism main shaft, knife-like switch structure support, constitutes knife-like switch separating brake, feed motion light detection front end.Knife-like switch separating brake, combined floodgate light detect baffle plate and close, divide to do and sway or upper and lower translation with the knife-like switch moving contact.For specifying the process of knife-like switch motion detection method; Select carefully to state three insulation column knife-like switches by assigning to the making process that closes; The knife-like switch moving contact rotates to standard closing position 7.1 from standard separating brake position 7.7; Flash ranging goes out the 101010101010101 corresponding time variations of totally 15 variation switching values and each position; Detect on the baffle plate each fixed position, hole distance calculation at each switching value transformation period of relevant position and knife-like switch light and analyze each mechanical property in real time such as closing speed, operating position and contact final position mutually of knife-like switch, detect real-time separating brake mechanical property equally; Knife-like switch operating mechanism main shaft light detect baffle plate at knife-like switch by assigning to the making process that closes; Begin to rotate in the main shaft rotation process 6.5 position to standard closing position 6.7 by standard separating brake position 6.2; Flash ranging goes out the 0101010101 corresponding time variation of totally 10 variation switching values and each position, calculates each mechanical property of operating mechanism.Light that knife-like switch appoints occurs and detect and take place and other two-phase and main shaft operating mechanism have been accomplished respective detection, judge that then knife-like switch one misplaces mutually; Knife-like switch three-phase light occurs and detect and take place and the main shaft operating mechanism has been accomplished respective detection, judge that then knife-like switch does not move and the fault that transmission has broken away between main shaft operating mechanism and isolating switch takes place.The each knife-like switch action of wall controller and background monitoring server stores mechanical property compares, and can draw knife-like switch running status or fault type and repair based on condition of component parameter.
