Description
Предметом изобретени вл етс приспособление дл пристройки сигнально-блокировочных контактов аварийного отключени к масл ному выключателю ВМГ-133, снабженному ручным рычажным приводом типа РБА.The subject of the invention is a device for extension of the emergency shutdown signal-blocking contacts to the oil switch VMG-133, equipped with an RBA type manual lever actuator.
Описываемое приспособление применимо дл масл ного выключател , имеющего механический блинкер, указывающий положение масл ного выключател . Приспособление устран ет необходимость установки сигнальных реле дл сигнализации об аварийном отключении масл ного выключател .The described device is applicable to an oil switch having a mechanical blinker indicating the position of the oil switch. The device eliminates the need to install alarm relays to signal the emergency shutdown of the oil switch.
Снабжение привода РБА описываемым приспособлением упрощает электрическую схему сигнализации № блокировки масл ного выключател .The supply of the RBA actuator with the described device simplifies the wiring diagram of the alarm signaling circuit No. of the oil switch.
На фиг. 1 изображено приспособление дл пристройки сигнальноблокировочных контактов в разрезе; на фиг. 2 - то же, вид сбоку; на фиг. 3 - блинкер с развилкой.FIG. 1 shows a device for extension of signaling contacts in the section; in fig. 2 - the same, side view; in fig. 3 - blinker with fork.
Дл получени аварийного сигнала при отключении масл ного выключател под действием защиты служат аварийные контакты /, св занные т гой 2 с развилкой 3 механического блинкера 4, укрепленной на оси 5.To obtain an alarm when the oil switch is turned off, under the effect of protection, there are emergency contacts / connected by a pull 2 with a fork 3 of the mechanical blinker 4 fixed on the axis 5.
Подвижна ось 6 сохран ет свое крайнее левое положение 6а (см. фиг. 1), указанное на чертеже пунктиром, при ручном включении и отключении масл ного выключател ; при этом механический блинкер 4 находитс в опущенном вниз положении. При отключении масл ного выключател под действием защиты ось 6 занимает крайнее правое положение, вследствие чего механический блинкер 4 устанавливаетс горизонтально. При повороте развилки 3 происходит замыкание или размыкание аварийных контактов /.The movable axis 6 retains its leftmost position 6a (see Fig. 1), indicated by a dotted line in the drawing, when the oil switch is manually turned on and off; while the mechanical blinker 4 is in the down position. When the oil switch is turned off under the action of protection, the axis 6 occupies the extreme right position, as a result of which the mechanical blinker 4 is installed horizontally. When turning fork 3, the emergency contacts are closed or opened.
