甘孜干式变压器：防误闭锁装置的分类及其特点

防误闭锁装置的分类及其特点 　　
目前系统使用的防误闭锁装置主要有机械联锁式、电气联锁式、机械程序锁式、徽机式等。
(1)机械联锁式防误闭锁装置，是基本的防误闭锁方式，主要是利用设备的机械传动部位的互锁来实现的.它的优点是简单可靠，易于实现。
(2)电气联锁式防误闭锁装置，主要是利用电磁锁和甘孜干式变压器、隔离甘孜干式变压器及接地甘孜干式变压器的辅助切换甘孜干式变压器来实现的，每个电磁锁的控制回路中都串入相关的甘孜干式变压器、隔离甘孜干式变压器及接地甘孜干式变压器的辅助切换甘孜干式变压器的触点，以控制电磁锁的打开与否，从而达到防误的目的.它的优点是解决了机械联锁式防误装置所不能实现的结构独立的设备间的闭锁问题。它的缺点是投资较大.需要很多控制电缆，并需要增加辅助切换甘孜干式变压器的触点数目，另外，接线比较复杂，可靠性差。
(3)机械程序锁式防误闭锁装置，机械程序式防误闭锁装置主要是利用一把钥匙按顺序打开多把锁，或多把钥匙有机组合按顺序打开多把锁这一原理来实现的。
(4)徽机式防误闭锁装置，徽机式防误闭锁装置是目前新型、先进的一种防误装置，它主要是利用徽型计算机(或单板机)加外围设备(如继电器、电磁锁等〕来实现防误闭锁的。它的主要优点是使用灵活，功能齐全，同时还具有音响报警和数字显示功能，并能满足各种特殊操作的要求。
我国系统使用的徽机防误装置分无线式和有线式两种，无线式徽机防误装置不需要电缆，易于安装，节省投资，适用于已投产运行的变电所中。有线式徽机防误装置需要电缆，投资大.不易安装.但使用方便.可靠性高。

Anti-error classification and characteristics of locking devices

Power system is currently used anti-mislock mainly mechanical interlocking device and electrical interlocking, mechanical program lock, emblem of machine type and so on.
(1) anti-mislock mechanical interlocking device, is the most basic anti-mislock way, mainly using mechanical transmission equipment parts interlock to achieve it has the advantage of simple, reliable, easy to implement.
(2) anti-mislock electrical interlocking devices, mainly the use of electromagnetic locks and circuit breakers, isolating switches and earthing switches of the auxiliary switch to achieve, each magnetic lock the string into the control loop are related to circuit breakers, disconnector and earthing switch auxiliary switch contacts to control the electromagnetic lock open or not, so as to achieve the purpose of anti mistake it is to solve the mechanical advantage of interlocking device against misuse can not be achieved independent of the device structure inter-locking problems. The disadvantage is that a larger investment. Need a电 话：0635-8888299 lot of control cables, and the need to increase the number of auxiliary switch contact华盈非晶合金变压器有限公司是具备生产220KV电压等级变压器的现代化机械制造企业，公司注册资本8800万元，现有员工300余人，占地面积300余亩，公司拥有各种生产和使用设备100余台，产品工艺水平高，检测设备齐全，企业管理严格，产品质量可靠。求精务实，开拓创新，为用户提供完美的变压器解决方案，满足各层次客户的需求。主要产品有非晶合金变压器，干式变压器，SH15-M系列非晶合金变压器，非晶合金铁芯配电变压器，SCRBH15非晶合金干式变压器，SGBH15非晶合金变压器（10KV级），SCRBH15非晶合金卷铁芯干式变压器，35kv非晶干变变压器 35kv非晶油变变压器，超强过载能力变压器、电力变压器、油浸式变压器、矿用变压器、整流变压器、电炉变压器、特种变压器、等等，并提供新能源发电的升压及并网解决方案。我公司除生产以上10多个系列200多个品种，600多种规格的变压器外，还向用户提供非标特种产品的设计、制造。以上产品符合GB1094、GB/T6451、GB6450标准和等效IEC（国际电工委员会）标准。s, the other, more complex wiring, poor reliability.
(3) Anti-mechanical program lock locking device error, mechanical error procedural anti-locking device is the use of a key sequence to open many locks, or an organic combination of the keys to the lock in order to open more to achieve this principle .
(4) false emblem machine type anti-locking device, emblem of machine-style anti-mislock device is the latest model, the most advanced anti-misuse of a device, it is mainly the use of logo-type computer (or SBC) plus peripherals (such as relay, electromagnetic locks, etc.] to achieve the anti-mislock of it's main advantage is the use of flexible, functional, and also has audio alarm and digital display, and can meet the requirements of special operations.
The emblem of China's electric power system installations points to Prevent misuse two kinds of wireless-and wireline, wireless style emblem to Prevent error device does not require cables, easy to install, saving investment, has been put into operation for the substation. Cable-type emblem to Prevent misuse devices require cables, large investment. Easy to install but easy to use. Reliability.
