Description

Примен емые в насто щее врем  индикаторы электрического напр жени , например типа УВН-80, во взрывоопасных местах могут вызвать взрыв газа вследствие образовани  искры при соприкосновении металлического наконечника индикатора с испытываемым объектом.Currently used electrical voltage indicators, such as the UVN-80 type, in explosive areas can cause a gas explosion due to the formation of a spark when the metal tip of the indicator touches the object under test.

Предлагаемый индикатор электрического напр жени  не имеет указанного недостатка. Взрыв горючего газа в окружающем пространстве при использовании данного индикатора невозможен, что достигаетс  применением у индикатора тонкостенного колпачка из изол ционного материала вместо металлического наконечника.The proposed electrical voltage indicator does not have this disadvantage. The explosion of a combustible gas in the surrounding space using this indicator is impossible, which is achieved by using a thin cap of insulating material on the indicator instead of a metal tip.

На чертеже показано устройство индикатора, который состоит из тонкостенного контактного колпачка / из пресс-материала К-18-2, заменивщего металлический наконечник, неоновой лампы 2 типа УВН-1, защитной трубки 3, конденсаторной трубки 4 и держател  5.The drawing shows the indicator device, which consists of a thin-walled contact cap / of press material K-18-2, replacing a metal tip, a neon lamp 2 of the type UVN-1, a protective tube 3, a capacitor tube 4 and a holder 5.

Индикатор электрического напр жени   вл етс  ручным переносным прибором, основанным на свечении неоновой лампы при касании колпачка / к объекту высокого напр жени , и служит дл  проверки наличи  или отсутстви  напр жени  в установках с номинальным напр жением бкв и с коэффициентом искробезопасности 2,5.The electrical voltage indicator is a handheld portable device based on the glow of a neon lamp when the cap is touched / to a high voltage object, and is used to check the presence or absence of voltage in installations with a nominal voltage of 2.5 kV.

Предмет изобретени Subject invention

Индикатор электрического напр жени , содержащий газосветную электрическую лампу, заключенную в закрытую трубку с окном дл  наблюдени  за свечением, отличающийс  тем, что, с целью повыщени  безопасности, применен тонкостенный колпачок из изол ционного материала, установленный на рабочем конце трубки.An electrical voltage indicator containing a gas-light electric lamp enclosed in a closed tube with a window for observing the glow, characterized in that, in order to increase safety, a thin-walled cap of insulating material is used that is installed on the working end of the tube.
