Transformer Conservator Tank & Breather Installation Guide
1. Key Components Overview of Transformer Breather
| Component | Function | Key Point |
|---|---|---|
| Conservator Tank (Oil Tank) | Stores and balances transformer oil volume | Must maintain correct oil level |
| Silica Gel Breather | Removes moisture from incoming air | Prevents oil contamination |
| Breather Pipe | Connects tank and breather | Must be vertical & sealed |
| Oil Cup (Seal Oil Chamber) | Blocks humid air entry | Filled with transformer oil |
| Isolation Valve (Optional) | Maintenance isolation | Used during servicing |
2. Installation Steps (Easy Guide)
| Step | Action | Installation Requirement |
|---|---|---|
| 1 | Install Conservator Tank | Fix securely on transformer top frame |
| 2 | Connect Breather Pipe | Ensure airtight and vertical connection |
| 3 | Mount Breather | Must be installed upright (oil cup at bottom) |
| 4 | Add Oil to Cup | Fill 1/3 to 1/2 level with transformer oil |
| 5 | Tighten Flanges | Use gasket + cross-tightening method |
3. Working Principle for Transformer Moisture Protection System
| Condition | Airflow Direction | Function |
|---|---|---|
| Transformer Cooling | Outside air → breather → tank | Moisture absorbed by silica gel |
| Transformer Heating | Tank air → breather → outside | Moisture filtered before release |
4. Silica Gel Color Indicator (Maintenance Guide)
| Color | Status | Action Required |
|---|---|---|
| Blue / Orange | Dry & Active | Normal operation |
| Pink | Moisture absorbed | Monitor closely |
| White / Transparent | Fully saturated | Replace immediately |
5. Installation Checklist (Quick Inspection)
- ✔ Breather installed vertically
- ✔ Oil cup filled correctly (1/3–1/2 level)
- ✔ No air leakage in pipe system
- ✔ Flange connections tightly sealed
- ✔ Silica gel in normal condition
- ✔ No oil leakage observed
6. Common Installation Mistakes (Avoid These)
| Mistake | Risk |
|---|---|
| Breather installed upside down | System failure |
| No oil in oil cup | Moist air enters transformer |
| Loose flange connection | Air leakage & contamination |
| Ignoring silica gel color change | Reduced insulation performance |
