Product Description

Based on the MURRAY bridge principle, the high-voltage bridge cable fault locator is specifically designed to identify breakdown points in various laid wires and cables, as well as defect points with low insulation resistance, even those that have not broken down. It is also applicable in cable factories to locate cable defects. The device incorporates a switching power supply to create a high-voltage constant current source, with a no-load voltage of 15KV and a short-circuit current of 50mA. A high-sensitivity amplifier and galvanometer are used for balance indication, while a proportional potentiometer forms the balance bridge. The entire assembly operates at a high potential, and the measurement cable is a specially designed double-core high-voltage rubber cable that uses the four-terminal resistance measurement method to eliminate errors from lead resistance. The cable is reliably grounded through its braided shielding layer. For safety, the operation button on the panel is at a low potential, and the bridge is operated using an insulating rod. The high-voltage constant current source and bridge are integrated into a portable aluminum alloy case, making the device lightweight, easy to operate, and safe to use. Compared to the wave reflection method, the bridge balance method has no blind area and is particularly suitable for detecting breakdown points in short cables and near the cable ends, with easy operation.

The output voltage is adjustable;
The shock frequency is adjustable;
With overcurrent protection;
There is no blind spot in the test range;
Signal frequency adjustment;
Zero protection.
High-voltage bridges are particularly suitable for
1. The high-resistance breakdown point of the cable after laying, especially the linear high-resistance breakdown point that is difficult to burn low-resistance, such as the linear high-resistance breakdown of the cable intermediate joint.
2. Flashover type breakdown point. After the breakdown, the constant current source can maintain the arc, a stable current flows through the bridge, and the bridge has sufficient sensitivity.
3. The defect points that have not yet broken down but have low resistance, such as the insulation defect points that have low resistance value of the cable but do not break down under the operating voltage are found by using a megohmmeter.

Due to the above characteristics, high-voltage high-voltage bridges are especially suitable for the following users:
Teams engaged in professional positioning: such as cable repair and trial classes for large and medium-sized power supply bureaus and large-scale electricity enterprises. Most of the cable breakdown points can be quickly found with a high-voltage bridge to find the approximate breakdown location. It can be used in conjunction with the wave reflection method and the fixed point meter to learn from each other's strengths and make the positioning faster and more reliable.
1. Small users: such as small power supply bureaus and medium-sized electricity enterprises. There are not many cables, the general direction is clear, the instrument is not located, the price is high, and the quality and experience of the user are required to be high, so it is not the best choice. It is a better way to choose this device, which is easy to operate and can meet daily needs.
2. Cable production plant: In the factory, it can be used to locate the breakdown point of various cables, and a digital capacitance meter can be selected to find out the disconnection point. The device is light in weight and easy to carry to the field for positioning services for cable users.
