10KV开关柜二次原理图详解.

常开(动合)按钮电路符号SB1-1控制器件-按钮常闭(动断)按钮电路符号SB复合按钮：常开按钮和常闭按钮做在一起。复合按钮SB常开(动合)按钮电路符号SB常闭(动断)按钮电路符号SB复合按钮：常开按钮和常闭按钮做在一起。复合按钮SB1-2控制器件-按钮常开（动合）触头常闭（动断）触头电路符号S和QF电路符号S和QF用作电路的限位保护、行程控制、自动切换等。1-3控制器件-微动和辅助开关结构与按钮类似，但其动作要由机械撞击。继电器和接触器的工作原理一样。主要区别在于，接触器的主触头可以通过大电流，而继电器的触头只能通过小电流。所以，继电器只能用于控制电路中。继电器类型中间继电器电压继电器热继电器（做过载保护）时间继电器（具有延时功能）电流继电器……1-4控制器件-继电器类型接触器控制对象：电动机及其它电力负载。接触器技术指标：额定工作电压、电流、触点数目。线圈KM常开常闭辅助触头－－用于控制电路（流过的电流小，无需加灭弧装置）KM接触器主触头－－用于主电路（流过的电流大，需加灭弧装置）KM1-5控制器件-接触器、继电器有关符号1-6控制器件-时间继电器类型瞬时动作常闭触点常开触点通电延时式常闭通电后延时断开常开通电后延时闭合断电延时式常闭断电后延时闭合常开断电后延时断开1首先了解工艺过程及控制要求；2搞清控制系统中各电机、电器的作用以及它们的控制关系；3控制电路中，根据控制要求按自上而下、自左而右的顺序进行读图或设计；4原理图上所有电器，必须按国家统一符号标注，且均按未通电状态表示；5继电器、接触器的电压线圈只能并联，不能串联；6控制顺序只能由控制电路实现，不能由主电路实现。1-7控制器件-继电接触控制电路读图和设计中应注意的问题：L+L-INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFQFHQKOQFQFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1IN2-1分闸合闸-初始状态QA1断开SA置于就地1、2接通开关在运行位置S9接通（试验位置S8接通）储能弹簧未储能L+L-INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFQFHQKOQFQFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1IN2-2分闸合闸-回路加电合上QA12-3分闸合闸-回路加电INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1IN合上QA1Y1得电2-4分闸合闸-回路加电INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INS2闭合Y1得电2-5分闸合闸-回路加电INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INY1得电S2闭合绿灯亮2-6分闸合闸-储能INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INS2闭合储能电机得电Y1得电绿灯亮2-7分闸合闸-储能中INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INS2闭合储能弹簧拉伸中Y1得电绿灯亮2-8分闸合闸-储能完成后INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INS2闭合储能电机停转S1闭合S3闭合S3断开S2断开黄灯亮Y1得电绿灯亮储能完成进行合闸2-9分闸合闸-合闸中INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INS2闭合储能电机停转S1闭合S3闭合S3断开S2断开黄灯亮Y1得电绿灯亮合闸线圈得电KO绿灯灭QF2-10分闸合闸-真空开关合上后INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2QFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INS2闭合储能电机停转S3闭合S3断开S2断开黄灯亮Y1得电合闸线圈失电QF开关辅助接点变换红灯亮QF断开S1闭合QF闭合QF2-11分闸合闸-真空开关合上后机械能量释放INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INS2闭合储能电机运转储能S1断开S3闭合S3接通S2接通黄灯灭Y1得电绿灯灭合闸线圈失电QF开关辅助接点变换红灯亮QF接通断路器合位指示灯亮QF2-12分闸合闸-储能电机重新运转储能后INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1IN储能电机停转S3断开S2断开QFS1接通黄灯亮QF2-13分闸合闸-分闸INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INQF按下SB2QF2-14分闸合闸-分闸中INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFHQKOQFL+L-QFTQY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INQFTQ得电开关分闸在开关合闸过程中分闸弹簧已经被拉伸储能。QF2-15分闸合闸-分闸后INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFHQKOQFL+L-QFTQY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INQFQF接通绿灯亮QF3-1防止开关跳跃原理S2S3QA1QA1PMLSB1KOQFHQKOL+L-10KV负载ABC按下SB110KV真空开关QFS2S3QA1QA1PMLSB1KOQFHQKOL+L-10KV负载ABC10KV真空开关HQ得电按下SB13-2防止开关跳跃原理KO4QFS2S3QA1QA1PMLSB1QFHQKOL+L-真空开关合上10KV负载ABCQF接通KO得电12QF断开按下SB13-3防止开关跳跃原理QFS2S3QA1QA1PMLSB1KOQFHQKOL+L-真空开关合上10KV负载ABCQF接通KO得电KO1、4接通124QF断开按下SB13-4防止开关跳跃原理QFS2S3QA1QA1PMLSB1KOQFHQKOL+L-10KV负载ABC124同时由于机构或负载有故障。在操作时造成开关合不上或事故跳闸按下SB1时间过长或无法返回时3-5防止开关跳跃原理QFS2S3QA1QA1PMLSB1KOQFHQKOL+L-同时由于机构或负载有故障。在操作时造成开关合不上或事故跳闸10KV负载ABCQF断开KO持续供电仍然保持回路接通124QF接通按下SB1时间过长或无法返回时HQ无法得到电压，开关不能再次合闸，防止了开关的多次分合3-6防止开关跳跃原理QF4-1继电保护-过流INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INQF速断过流备用重瓦斯接点重瓦斯跳闸QF4-2继电保护-过流INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INQF当线路电流和时间超过过流整定值时203204205206SEL205QF4-3继电保护-过流INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELXB1XB2XB3QFWSKCOSELKA1INQF203204206SEL的205-206接通KCO得电SEL205QF4-4继电保护-过流INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFHQKOQFL+L-QFTQY1S9S8S2S31HL22HL23HL2MSELSELXB1XB2XB3QFWSKCOSELKA1INQF203204206SEL的205-206接通KCO得电KCO闭合TQ得电SEL205QF4-5继电保护-开关跳闸INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELXB1XB2XB3QFWSKCOSELKA1INQF203204206SEL的205-206返回开关的辅助接点全部转换绿灯亮红灯灭断路器合位指示灯灭KCO失电KCO断开QF3-6继电保护-速断INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INQF当线路电流和时间超过速断整定值时SEL的203-204接通动作过程用过流203204205206QF4-7继电保护-重瓦斯INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSELSELSELXB1XB2XB3QFWSKCOSELKA1INQF当变压器内部发生故障时WS接通203204205206QF4-8继电保护-重瓦斯INS1S2S3QA1QA12156SALRKA1XB4KCOSELPMLPMLSB1SB2KOQFHQKOQFL+L-QFOFFY1S9S8S2S31HL22HL23HL2MSE
