摘　　要：保护校验是继电保护常规工作,根据实际工作性质又可具体分为投产校验、定期校验、改定值和补充校验等,均须进行接线试验。保护校验必须停电进行,而保护校验时间长短直接影响了设备停电时间。为了确保设备停送电及时性,提升供电可靠性,进一步优化营商环境,制作了一种新的试验线线盘及线箱,应用后有效缩短保护校验接收线的时间,避免了接线缠绕等安全隐患,具有很高的推广价值。Relay protection verification is a kind of routine work including first verification,regular verification,addition-al verification and changing settings erc.All these verifications need to connect and disconnect wires.Relay protection verification needs poweroff and the verification hours relate to poweroff hours.ensuring poweron on time,improving the power supply reliability and making the business environment batter,new verification wire disc and box are made.Using these new tools,the verification hours are shortened,the potential risks are reduced.It's worth to spread widely.
