Problems solved by technology

However, in explosive hazardous places, since the turn signals in the headlights of automobiles are non-explosion-proof products, their use must be restricted and cut off on the circuit. At this time, it is not a bulb failure, but the frequency of the flasher is also accelerated.

Abstract

The invention discloses a power compensator for a flasher. The power compensator comprises a shell, a switching circuit and a power compensation circuit conductively connected with the switching circuit, wherein the switching circuit and the power compensation circuit are located in the shell which is in a pouring structure; and the shell is internally provided with a voltage limiting circuit and a temperature protecting circuit. An anti-explosion fire truck using the power compensator comprises a cab, wherein the flasher and the power compensator are arranged on the front part of the cab. The power compensator for the flasher is arranged so that the flasher does not alarm mistakenly and has a good anti-explosion performance. The power compensator for the flasher can be applied to explosive dangerous environments. As the power compensator for the flasher is arranged on the flasher of the fire truck which uses the power compensator for the flasher, the power compensator for the flasher can be applied to explosive dangerous environments.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof automobiles, in particular to a flasher power compensator and an explosion-proof fire truck using the power compensator. Background technique [0002] When an explosion-proof fire truck (vehicle) is used in an explosive hazardous location, every electrical and non-electrical component on the vehicle should be an explosion-proof electrical component that does not generate high temperature and (static) electric sparks and other dangerous factors. At present, the flasher used in the car is a control device that controls the flashing frequency of the turn signal when the car turns. The flasher has the bulb fault diagnosis function. When a turn signal on a certain side fails, the flashing frequency on that side will increase. However, in explosive hazardous places, since the turn signal in the headlight of the car is a non-explosion-proof product, its use must be restricted and cut off on the ...
