Dual analog circuit breaker

dual-pathSimulated circuit breakerAdopt the latestARMmicrocontrollerA 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.

OneDual analog circuit breakerPerformance Characteristics

1．Dual analog circuit breakerEquipped with high-precision programmable DC voltage regulator and constant current power supply,For users to use when there is no DC power supply(Optional).

2． Dual analog circuit breakerCan be operated through single touch screen, single tablet, mobile phone, touch screen+Tablet or mobile phone operation (please select when ordering)

3．Dual analog circuit breakerhaveATheBTheCandDTheETheFtwo 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．dual-pathSimulated circuit breakerThe input control terminal can input AC/DC current signals to trigger the analog circuit breaker action. Thus, the operating characteristics of AC/DC circuit breakers can be simulated. Greatly convenient for users.

5．Dual analog circuit breakercan pass throughuExport test data to the computer via disk.and 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．Dual analog circuit breakerAdopting 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．Dual analog circuit breakerAdopting 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.

Dual analog circuit breakerCan simulate the automatic reclosing test of AC/DC circuit breakers、Automatic commissioning test of backup power supply、Three phases in different periodswaitexperiment.
