Product Description

Dary Electric recommends for you

Three-phase relay protection microcomputer type test device is an important testing tool to ensure the safe and reliable operation of the power system. With the rapid development of computer technology, microelectronics technology, and power electronics technology, it is an inevitable trend of technological progress to continuously introduce new high-performance relay protection test devices with applied technological achievements.

It is developed based on the "Technical Conditions for Microcomputer Relay Protection Test Devices" issued by the former Ministry of Electric Power, extensively listening to the opinions of Shanghai Rixing Electric Co., Ltd., carefully summarizing the development and production experience of previous generations of products, and adopting modern digital technology, high-precision electronic devices, microcomputer systems, and new circuits,

and new structures. It can independently complete device testing in professional fields such as microcomputer protection, relay protection, excitation, metering, and fault recording, and is widely used in scientific research, production, and electrical test sites in industries such as electric power, petrochemical, metallurgy, railway, aviation, and military.

It is divided into two circuits: the main circuit and the auxiliary circuit. The main circuit is adjusted by a large knob, and the auxiliary circuit is adjusted by a small knob. The main circuit controls the various output quantities through the "Output Selection" button switch on the panel, and each time the output is switched, the digital voltage/current meter on the instrument can automatically monitor its output value.

The auxiliary circuit is directly adjusted through the output switch control, and measurement can be performed with an external multimeter.

It is a new type of miniaturized microcomputer relay protection test instrument developed based on the "Technical Conditions for Microcomputer Relay Protection Test Devices (Discussion Draft)" issued by the Ministry of Electric Power, extensively listening to user opinions, summarizing the advantages and disadvantages of similar domestic products, and fully utilizing modern advanced microelectronics technology and devices.

It adopts an advanced structure that can operate independently as a single unit or be connected to a laptop for operation. The host is equipped with a new generation high-speed digital signal processor microcomputer, a true 16-bit DAC module, a new modular high-fidelity high-power amplifier, a built-in large-screen LCD display, and a flexible and convenient rotary mouse controller.

Standalone operation already has strong functions and can perform most tests, while connecting to a computer provides more powerful operation functions. It is small in size and high in precision.
