关于SR469-P5-HI-A20-E的常见问题

GE SR469-P5-HI-A20-E电机管理继电器的热容量偏置和偏置K因子不平衡应如何处理?

GE SR469-P5-HI-A20-E电机管理继电器具有热容量的不平衡偏置，它应该启用热容量使用，因此不平衡偏置电流的加热效应被添加到热容量中。对于不平衡偏置K因子，该值是通过由于K因子不平衡而在转子中流动的负电流的贡献来计算的。有一个公式是基于经验的数据统计到字母“K”，它等于230除以每单位锁定转子电流的平方。锁定转子安培= 631% FLA或6.31乘以FLA。

SR469-P5-HI-A20-E继电器的冷热曲线比是多少?

利用SR469-P5-HI-A20-E继电器的数据表，设置安全失速冷热时间曲线比为16/18，等于0.89。用热安全失速时间除以冷安全失速时间简单计算出冷热曲线比，也可采用电机热极限曲线。

SR469-P5-HI-A20-E继电器的电阻温度检测器偏置最大额定值是多少?

电阻温度检测器偏置最大额定值是设置在绝缘额定值或设置略低的设置。为了将电阻温度检测器的最大偏置设置为F级绝缘，电机的额定温度为155摄氏度。

Product description

The SR469-P5-HI-A20-E is from GE Multilin and is part of the SR469 motor management relay line. The unit is designed with a 5 amp phase CT secondary circuit. The SR 469 relay is designed for use in medium voltage motors and provides integrated management and protection. AX Control maintains an on-hand inventory of several different Multilin SR 469 relays.

The SR469-P5-HI-A20-E offers 70-265 VAC, 90-300 VDC control power. This unit has an enhanced front panel. However, if you need a unit that can be used in harsh environments, see our SR469-P5-HI-A20-E-H listing, which is like this unit in every way except for the additional harsh environment conformation coating.

The SR469-P5-HI-A20-E has a well-designed front panel that provides ease of use. The panel includes an RS-232 program port interface with a baud rate of 9600 and programmable up to 19,200 baud. This panel has a pull-out handle that can be sealed to prevent any kind of unauthorized movement. The front panel has a large LCD screen that can display 40 characters. Users can see diagnostic information such as tripping or alerts locally through this display. In addition, the panel features motor and output status indicators, unit indicators, numeric keypad, control and programming keys, including reset, escape and menu buttons, and value keys that allow the user to change set values.

Frequently Asked Questions about SR469-P5-HI-A20-E

GE SR469-P5-HI-A20-E Motor management relay thermal capacity bias and bias K factor imbalance should be dealt with?

The GE SR469-P5-HI-A20-E motor management relay has an unbalanced bias of the heat capacity, which should enable the heat capacity use, so the heating effect of the unbalanced bias current is added to the heat capacity. For unbalanced biased K-factors, the value is calculated by the contribution of the negative current flowing in the rotor due to the unbalanced K-factor. There is a formula based on empirical data statistics to the letter "K", which is equal to 230 divided by the square of the current per unit of locked rotor. Locking rotor ampere = 631% FLA or 6.31 times FLA.

What is the cold/heat curve ratio of the SR469-P5-HI-A20-E relay?

Using the data sheet of the SR469-P5-HI-A20-E relay, set the safe stall cold/hot time curve ratio to 16/18, equal to 0.89. The ratio of cold and hot curves can be calculated simply by dividing the thermal safe stall time by the cold safe stall time, or the thermal limit curve of the motor can be used.

What is the maximum resistance temperature detector bias rating for the SR469-P5-HI-A20-E relay?

The resistance temperature detector bias maximum rating is set at the insulation rating or set to a slightly lower setting. In order to set the maximum bias of the resistance temperature detector to Class F insulation, the motor is rated at 155 degrees Celsius.
