Description

Изобретение относитс  к устройствам дл  сигнализации о наличии напр жени  в цеп х напр жени  релейной защиты и измерительных цриборов на подста-нци х с двум  несекционированными системами ши.н, одна .из которых резервна .The invention relates to devices for signaling the presence of voltage in the relay protection voltage circuits and measuring instruments at subbases with two non-sectional systems, one of which is redundant.

Согласно .изобретению, , пере1и1 .ючени  указанных цепей напр жени  при переходе на работу с одной системы шин на другую предлагаетс  примен ть оди-н общий переключатель , снабженный дополнительными контактам.. Указанные контакты включаютс.  последовательно с сигнальным прибором в оперативную цепь -реле напр жени  каждой системы шин так, что питан .ие сигнального прибора осуществл етс  при .перего.рании предохранител  в цепи напр жени , тик и при несоответствии положени  переключател  режиму работы шин.According to the invention, the switch 1 of the indicated voltage circuits, when switching from one bus system to another, proposes to use a single common switch equipped with additional contacts. The contacts are included. in series with the signal device in the operational circuit - relay of each bus system voltage, so that the signal device is powered when the fuse is interrupted in the voltage circuit, tick and if the position of the switch does not match the bus operation mode.

На чертеже приведена принципиальна  электрическа  схема предлагаемого устройства.The drawing shows the principal electrical circuit of the proposed device.

При переходе на работу с одной системы шин на другую цепь напр жени  релейной защиты и измермтельных приборов переключаетс  сWhen switching from one bus system to another, the voltage circuit of the relay protection and measuring devices switches from

The contacts a, c, d, e of this switch perform the usual functions of connecting voltage circuits to a TOY or other spike system. The contact in the case of; 1, l makes a signaling about the presence of voltage in the indicated voltage circuits and is connected in series with the contacts of the intermediate relay P, and Pj into the circuit of the signal device SP. The coils of the intermediate relays P and P-i: include dyucheny in opereratnivnuk) relay circuit voltage f /., And and lindens of each tire system. At the same time, the intermediate relays PI and RZ have such a contact system that the power supply circuit of the signal device; When one of the relays is turned on (in this case, PI) it closes only in those cases when it is ignited; the 11th switch does not correspond to the spike mode of operation. The closure of this circuit also occurs when the corresponding voltage relay is triggered and the PM-controlled intermediate relay (in this case, PI) shuts down due to a blown fuse in the voltage circuit.
