Based on the introduction and adoption of foreign advanced technology, Shenhai has developed an insulation monitor suitable for the Chinese electric vehicles market. The car monitor continuously monitors the insulation resistance of the positive and negative buses of the HVDC system to the ground and sends out alarm signals when the set response value is reached, so as to ensure the safe operation of the personnel and vehicles. According to the different voltage of the applicable auxiliary power supply, this product has three series: 12V, 24V, 9 ~ 36V.
Auxiliary power supply voltage range9-18v or 18-36V or 9-36v;
High voltage DC voltage:0-800 VDC
Operating temperature:- 40 掳 C to + 85 掳 C
Storage temperature:- 40 掳 C to + 85 掳 C
Protection grade:IP55 (dust and splash proof)
Measurement range of insulation resistance:0k 惟 ~ 50m 惟
Relative measurement error:卤 15% (100k 惟 ~ 10m 惟)
Measurement error:卤 10K 惟 (0k 惟 ~ 100k 惟)
Measurement response time:鈮?5 ~ 6S
(the condition is that the analog resistance = 100k 惟, y capacitance = 1uF and the bus voltage is stable)
鈼?Micro processor technique and intelligent design is used
鈼?Optimized measurement technique for low-frequency control processes
鈼?Real time online Measuring insulation resistance of the whole system
鈼?Automatic adaptation to the existing system leakage capacitance
鈼?Automatic device self test and calibrating
鈼?Three kinds of output available, PWM, CAN, and ALARM
鈼?Space-saving design, easy to install
鈼?Insulation monitoring for unearthed DC system( IT systems) 0...800V
鈼?Can achieve multi-channel detection(optional)
鈼?For 12V/24V low voltage supply vehicle
A positive and negative symmetrical square wave signal is generated in the insulation monitor. The measurement loop is composed of L1 / L2, e terminals and the insulation resistance RF between DC high voltage system and chassis. The change of current in the measurement loop can reflect the insulation resistance of DC high voltage system to ground. As shown in Figure.
