游丝是许多电测仪表的重要元件。更换游丝是电表修理中经常遇到的修配工序。选配游丝通常采用试验法和比较法。试验法是根据原有游丝的宽度和厚度、材料种类、圈数多少、内外圈直径等挑选新游丝,然后装在表上进行通电试验。根据仪表的示值情况决定是否可用:若示值偏大(即走动偏快),说明游丝力矩过小,应换力矩大的游丝;若示值偏小(即走动偏慢),说明游丝力矩过大,应换力矩小些的游丝。比较法,就
Gossamer is an important component of many electrical measuring instruments. Replacing the hairspring is the repair process often encountered in the meter repair process. Optional hairspring usually test method and comparative method. Test method is based on the original width and thickness of hairspring, material type, the number of turns, the diameter of the inner and outer rings pick a new spring wire, and then installed in the table on the power test. Determine if it is available according to the indication status of the instrument: If the indication is too large (that is, move too fast), it indicates that the hairspring moment is too small and the hairspring with larger moment should be replaced; if the indication is too small Too large, should change the moment less gossamer. Comparative Law, it
