Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of voltage transformer detection, and in particular relates to a voltage transformer high-voltage detection auxiliary device. Background Art
[0002] Voltage transformers are similar to transformers, and are instruments used to transform the voltage on a line. However, the purpose of transformers to transform voltage is to transmit electrical energy, so the capacity is very large, and is generally calculated in kilovolt-amperes or megavolt-amperes; while the purpose of voltage transformers to transform voltage is mainly to power measuring instruments and relay protection devices, to measure the voltage, power and electrical energy of the line, or to protect valuable equipment, motors and transformers in the line when a line fault occurs.
[0003] The voltage transformer has two windings, one is called the primary winding and the other is called the secondary winding. Both windings are installed or wound on the iron core. There is insulation between the two windings and between the winding and the iron core, so that there is electrical isolation between the two windings and between the winding and the iron core. When the voltage transformer is in operation, the primary winding N1 is connected in parallel to the line, and the secondary winding N2 is connected in parallel to the instrument or relay. Therefore, when measuring the voltage on the high-voltage line, although the primary voltage is very high, the secondary voltage is low, which can ensure the safety of the operator and the instrument. Its working principle is the same as that of the transformer, and the basic structure is also the iron core and the primary and secondary windings. The characteristics are that the capacity is very small and relatively constant, and it is close to the no-load state during normal operation. The impedance of the voltage transformer itself is very small. Once a short circuit occurs on the secondary side, the current will increase sharply and burn the coil. For this reason, the primary side of the voltage transformer is connected with a fuse, and the secondary side is reliably grounded to prevent the secondary side from having a high potential to the ground when the insulation of the primary and secondary sides is damaged, causing personal and equipment accidents. The voltage transformer needs to be tested for performance before installation. The performance test is mainly to detect whether the secondary voltage meets the standard. Most of the existing power testing vehicles use the traditional threaded locking wire method to connect the secondary voltage test instrument. When replacing the voltage transformer, the threaded fixings need to be twisted forward and backward to complete the power connection and power disconnection of the test instrument. The frequent twisting operation is cumbersome, laborious and inconvenient. Summary of the invention
