URF系列有载分接开关监控继电器

产品描述
有载分接开关监控继电器也被称为有载分接开关保护继电器或者油流继电器。它是一种对用油作为绝缘液带有储油柜有载分接开关进行监控的设备。它的作用是防止有载分接开关和变压器受到损坏。监控继电器对向储油柜方向超过规定值过高油流做出反应，并将发出信号，有载分接开关和变压器会立即无电压跳闸。

URF Series Monitoring relay for tap changers

PRODUCT DESCRIPTION
The monitoring relay for tap changers, also known as the protection relay for tap changers or oil flow relay, is a monitoring device for insulating liquid-filled tap changers with conservators. It protects the tap changer and the transformer from damage. The monitoring relay responds to excessive oil flow in the direction of the conservator and generates a signal disconnecting the tap changer and the transformer immediately from voltage supply.
Pipe diameter DN: 25 mm (1") Type of connection: flanged
Selected technical data:

Voltage: AC/DC 12 V to max. 250 V
Current: AC/DC 0.01 A to max. 2 A
Ambient temperature: - 40°C to + 55°C
Climate-proof version: extreme frigid open-air conditions below - 40°C; Offshore
IP code: IP 54, 56 or 66
Casing colour: RAL 7001, RAL 7012, RAL 7022, RAL 7033, RAL 7038, RAL 7035, RAL 7016, RAL 9002, RAL 7032

Response of the switching system in the case of:
Insulating liquid flow: damper setting: min. 0.9 to max. 4.00 m/s +/- 15% Damper held by magnets

Switching element: magnet contact tube Contact setting of the switching system: normally-open contact, normally-closed contact, change-over contact

Monitoring relay equipped with up to three magnet contact tubes (please, see cataloque for switching design options)
