How many open current transformers should be installed in the distribution box, do you know?
When we open the power distribution cabinet, we can see that there are many current transformers in it. Some power distribution cabinets have only one, and some even have five or six. In fact, they all induce current signals from the bus, but the measured currents have different effects. So what role do they all play in the power distribution cabinet?
Simply put, it is to effectively use the range of the voltmeter. For example, a voltmeter with a full scale of 75mv, the object to be measured is a current of about 20A, you choose the shunt resistance R, and R*20A should preferably fall on the middle of the 75mV range, such as 3mΩ to 3.5mΩ for comparison Suitable.
Enterprises adapt to mobile office
In many work links, such as quotation, after-sales, logistics, etc., during the epidemic, we did not completely press the pause button, but all departments worked together and cooperated to promote the promotion and development of business and various tasks.
Selection of Shunt Resistors
Due to its special function of shunt resistors, when used in precision electronic products, such as instruments, meters, and measuring devices, the resistor should be selected with special emphasis on accuracy. If the accuracy is not enough, it may cause the size of the shunt current to pass through a large Difference value projection, which directly leads to larger measurement errors, which would be meaningless measurements. In the same way, for other precision electronic information technology products, because the development of Chinese enterprises has high requirements, it is necessary for us to choose resistors with high precision.
In order to increase the cohesion of the company's employees, strengthen their sense of belonging, and promote employees' understanding and communication, so that each employee can truly feel the warmth of the big family of China Science and Technology after stressful work, the company organized employees with the theme of "Thanksgiving for you" Birthday party activities, to celebrate the birthday of employees in November, share happy moments!
The wire-wound chip inductor is based on the traditional wire-wound inductor production process, which transforms the plug-in inductor into a chip package, which reduces the volume of the inductor and is more convenient to use.
