Overview

The high temperature rise high current fire-resistant circuit breaker adopts a new type of high-power fidelity linear power amplifier circuit, with high output power and low ripple interference. Each phase voltage can output 120V and current can output 40A. When the output current reaches 40A, the output power can reach 450VA/phase or above, and the waveform can still ensure that it is true and not clipped.

Product Details

High temperature rise high current fire-resistant circuit breakerPerformance characteristics:

1) Built in high configuration industrial computer, using programmable logic controller Siemens PLC as the central processor, real-time scanning of AC signals, achieving comprehensive monitoring and closed-loop control, and designing password setting management. Only personnel with corresponding operating permissions can perform normal operations of certain functions.

2) The high current generator temperature rise test device adopts a 10 inch large LCD touch screen operation, and uses intelligent sensors that support fieldbus technology to achieve fully digital data transmission. The display and operation unit adopts a touch type color LCD display screen, with a full Chinese menu, clear and intuitive interface, and simple and convenient operation. Testing does not require any external auxiliary equipment, fully automatic control, foolproof operation, fast, simple, and convenient.

3) There are two testing methods for the high current generator temperature rise test device: fully automatic testing and manual testing. Simply set a simple test current and time, and it comes with an automatic current stabilization system. Reduced the possibility of potential malfunctions in complex button switches.

4) The high current generator temperature rise test device only needs to set the target current, without manual monitoring. Only the testing, current, and step size need to be set, saving tedious labor such as manual voltage regulation, manual recording, and curve drawing, reducing labor intensity, and improving work efficiency. After the work is completed, the data can be read to the computer for viewing.

5) The automatic alarm function for exceeding the limit value has reliable self-protection functions for overheating, overcurrent, overvoltage, and short circuit. The protection of the AC voltage regulating device should adopt dual protection of microcomputer automatic protection control and mechanical micro limit switch to ensure the normal operation of the constant current power supply and improve the safety and reliability of the product.

Maintenance suggestions:

1. Dustproof and moisture-proof

Provide appropriate dust and moisture prevention measures for circuit breakers, especially in humid environments. Moisture and dust may cause a decrease in insulation performance, affecting the reliability of circuit breakers.

2. Regularly inspect mechanical components

Check the mechanical components of the circuit breaker, including the spring mechanism, operating mechanism, etc., to ensure flexible operation and no jamming. The normal operation of mechanical components is the key to ensuring the normal operation of circuit breakers.

3. Record the number of operations

Regularly record the number of operations of the circuit breaker and replace worn parts as a preventive measure. Regular operation records help to detect problems in advance and reduce the risk of sudden failures.
