Safety indicator discharge bar

The invention provides a novel discharge bar capable of ensuring safety and indicating voltage, and the discharge bar overcomes the deficiencies of the prior art. The discharge bar adopts a double-ground-wire structure. A loop detecting device is added between two ground wires to check whether a ground wire loop is complete. The discharge bar adopts double light metal foils and a pointer type voltmeter double voltage indicating structure. Two voltage indicating modes are visual, clear and passive. Whether the voltage of a test object is still high is indicated. A pointer type voltmeter is protected by a discharge tube, is not damaged by overvoltage, and is free of maintenance. Test and maintenance personnel can carry out subsequent operation steps in the cases of low voltage and sufficientdischarge, so that the safety of the personnel is ensured. 本发明克服了现有技术存在的不足，提供了种新型的能够保障安全并且指示电压的放电棒。该放电棒采用双地线结构，并且在两个地线之间加上回路检测装置，能够检查接地线回路是否完整；该放电棒采用双轻质金属箔片和指针式电压表电压双指示结构，两种电压指示方式直观、清晰，无源，指示被试品是否仍有高压，指针式电压表通过放电管保护，不会因过电压损坏，不
