Study Notes
Company Information
- Maschinenfabrik Reinhausen is based in Regensburg, Germany.
- Contact includes a telephone number (0941 440-1) and telex number (65881).
- Affiliated with Gebriider Scheubeck GmbH & Co. KG.
Product Overview
- The document details inspection instructions for the On-Load Tap-Changer Type DA.
- Covers techniques for maintaining and ensuring the operational efficiency of tap-changer mechanisms.
Inspection Process
- Open the vent screw on the tap-changer head cover to facilitate inspection.
- Drain valve usage is crucial; oil should be drained until the energy accumulator is devoid of oil.
- Inspection can be aided by looking through an inspection window on the tap-changer head cover.
Maintenance Instructions
- After performing maintenance, ensure the holding pawl is secured and the fixing screw (M RD 135) is tight.
- For the energy accumulator spring:
- Loosen ten countersunk head screws (M5x10) and remove guiding rails.
- Withdraw the spring unit of the energy accumulator for inspection and replacement if necessary.
Safety and Compliance
- Rights regarding technical documents are reserved according to DIN 34, Section 2.1.
- Precautions are highlighted to prevent the interchanging of contact systems; numbers are indicated on support and guiding plates for identification.
Technical Details
- Document includes specific figures (e.g., fig. 19 & fig. 20) for visual guidance on maintenance procedures.
- Clear emphasis on meticulous adherence to detailed maintenance steps to ensure safety and functionality of equipment.
Inspection Guidelines
- Cleanliness and care are crucial during inspection work to ensure safety and efficiency.
- Diversion switches should not be exposed to air for longer than ten hours to prevent damage.
Tools Required
- Various socket and open-jaw wrenches are needed, including sizes 19, 17, 13, 10, 9, and 8.
- Allan keys are essential, specifically size 5 and 4, for certain components.
- A screwdriver, circlip pincers, locking pincers, and specific operating keys (for switch spindle and energy accumulator) are included in the toolkit.
- Additionally, two cocking hooks are part of the tool requirements.
Spare Parts Maintenance
- Regular inspections and replacements of shock absorber springs are necessary after every 100,000 switching operations.
- The energy accumulator spring also requires replacement after the same number of operations for optimal performance.
- Replacement of permanent main contacts is advised after 300,000 operations or if contact roller clearance reaches about 1 mm.
Gear Plate Installation
- When mounting the gear plate, installation must follow the reverse order of disassembly.
- The Geneva cam wheel should be installed carefully with sliding disks positioned between them for smooth operation.
- Secure fixing screws of the gear plate and coupling bolts without fail.
Control Work Procedures
- The state of the support cylinder and switch crank tube should be visually inspected using a hard paper template.
- Radial clearance measurement between roller bolt and roller must not exceed 0.6 mm for proper function.
Coupling and Mounting
- Coupling of the three diverter switches should follow the reverse order of disassembly, ensuring reference marks are used accurately for alignment.
- When mounting the supporting cylinder with the insert head, ensure it is positioned vertically and concentrically for correct functioning.
- Secure both separating flanges and bolting connections with lock washers to avoid loosening during operation.
Visual Inspections
- Carry out visual inspections of resistors and hard paper components to assess their condition.
- Regular check of the state of bristles, compression springs, and contact rollers is essential for long-term reliability.
