The high-voltage circuit breaker simulation device can be operated on a tablet or mobile phone

PRS-102MThe microcomputer based analog circuit breaker is the latest one adopted by our company on the basis of the original analog circuit breakerARMmicrocontrollerA new type of product developed as a control core. Because of the use of a new type of microcontroller, program control, and10.1inchThe 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 the equipment required 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.

OnePerformance 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(Optional).

2．This device can be operated through a single touch screen, a single tablet, a mobile phone, or a touch screen+Tablet or mobile phone operation (please select when ordering)

3．This device hasATheBTheCandDTheETheFtwo routesIndependent three-phase analog circuit breaker，It can be used as six switches during the backup self switching test，Generally, analog circuit breakers only provide one pair of normally open for each phase、Normally closed contact，According to the requirements of the backup self commissioning test, it is necessary to add output contacts.Additionally, due to the tripping of circuit breakers from different manufacturers、There is a difference in the closing time，According to the different needs of customers，The products produced by our companyPRS-102MMicrocomputer based high-voltage circuit breaker simulation device provides multiple functional options，This includes adding analog circuit breaker output contacts to two pairs of normally open and two pairs of normally closed contacts，Selection of multi range tripping and closing time and tripping and closing resistance, etc.

4．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.

5．This simulated circuit breaker can pass throughuExport test data to the computer via disk.And it hasRS-485Interface andSupporting Ethernet Modbus protocol communication, it can simulate the closing and opening control of circuit breakers through remote control in the background, and the background can also read the position information of simulated circuit breakers，It can be controlled through the upper computerOperation. (Can provide Android and HarmonyOS upper computer software)（This function is an optional feature, please specify it when placing an order）.

6．This simulated circuit breaker adopts a low-energy design，Built in large capacity lithium batteryCan be used continuously without AC power supply on site10More than hours，standby30More than an hourWhen 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）.

7．This device adopts modular design，Infinite expansion can be achieved by adding a tripping and closing module and control unit.Can be formed2Multiple 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 commissioning test of backup power supply、Three phases in different periodswaitexperiment.
