PRS-102M Intelligent Microcomputer Simulated Circuit Breaker

• Overview

PRS-102MThe microcomputer based analog circuit breaker is adopted by our company on the basis of the original analog circuit breakerARMA new type of product developed using a microcontroller as the control core. Because of the use of a new type of microcontroller, program control, and10.1The touch screen performs all parameter and switch operations, abandoning all mechanical buttons or knobs, thereby improving the accuracy and performance of the entire machine. This product has the characteristics of reliability, durability, easy wiring, small size, and light weight. It is equipment for testing relay protection devices. It can be used in conjunction with various microcomputer based relay protection testing devices to complete the experimental and testing work of complete sets of relay protection devices for various voltage levels in the power system relay protection department, ensuring the integrity and reliability of the complete set of relay protection devices and improving the calibration quality of the devices.

• Performance Characteristics

1. This machine comes with a high-precision programmable DC stabilized constant current power supply for users to use when there is no DC power supply.
2. This device hasATheBTheCandDTheETheFTwo independent three-phase analog circuit breakers can be used as six switches during backup self switching tests. Generally, each phase of the analog circuit breaker only provides one pair of normally open and normally closed contacts, and output contacts need to be added according to the requirements of backup self switching tests. In addition, due to the differences in the tripping and closing time of circuit breakers from different manufacturers, our company produces according to the different needs of customersPRS-102MThe microcomputer based high-voltage circuit breaker simulation device provides multiple functional options, including adding simulated circuit breaker output contacts to two pairs of normally open and two pairs of normally closed contacts, selecting multi range tripping and closing time, and selecting tripping and closing resistance.
3. This analog circuit breaker input control terminal can input AC/DC current signals to trigger the action of the analog circuit breaker. Thus, the operating characteristics of AC/DC circuit breakers can be simulated. Greatly convenient for users.
4. This simulated circuit breaker can pass throughuExport the test data to the computer. And it hasRS-485Interface, which can be controlled and operated through the upper computer（This function is an optional feature, please specify it when placing an order）.
5. This simulated circuit breaker adopts a low-energy design and is equipped with a large capacity lithium battery. It can be used continuously without AC power supply on site10More than hours, standby30More than an hour. When using internal power supply, the DC output power supply provided by this machine is not available（This function is optional, please specify it when placing an order）.
6. This device adopts a modular design, which can be infinitely expanded by adding tripping and closing modules and control units. can form2Multiple circuit breakers with multiple circuits or more can simulate the actions of multiple three-phase circuit breakers. Multiple analog circuit breaker input and output circuits are isolated from each other, and when the tripping and closing coil currents are used in parallel through corresponding channels, the current can be doubled, thereby achieving more functions. It can also be used to form a simulated circuit breaker screen for teaching and experimental purposes.

In summary, this simulated circuit breaker can simulate the automatic reclosing test of AC/DC circuit breakers, automatic backup power input test, and three-phase different period tests.
