Embodiment Construction
[0007] Such as figure 1 As shown, the 220V AC power provided by the mains passes through the switch K 1 And the fuse RD is connected, transformed into 110V AC by transformer B, and then converted to 110V AC by diode D 1 ~D 4 The composed rectifier bridge outputs a 110V DC power supply after rectification. The output terminal of the rectifier bridge is connected with an electrolytic capacitor C in parallel. After filtering through the electrolytic capacitor C, a stable 110V DC power supply is output. The DC output terminal of the rectifier bridge is connected in parallel with a resistor R 1 and power indicator LED 1 A series circuit, the resistor R 1 Is the power indicator LED 1 The current limiting resistor ensures that the power indicator light can work normally. When the power switch K 1 When closed, the power indicator LED 1 Lighting up indicates that the 110V power supply is normal and can work for the test device and the temperature control box; the present inventi...

The invention discloses an electric heating glass temperature control box test device, relates to an electric heating glass temperature control box test device used to debug a temperature control box temperature control system on front window glass of an internal combustion locomotive; and mainly aims to solves the problem that debugging is not accurate because conventional temperature control box temperature debugging on the front window glass of the internal combustion locomotive is directly in the internal combustion locomotive. According to the electric heating glass temperature control box test device of the invention, an output end of a 110V DC power supply is connected to a jack 5 and a jack 7 of a socket CZ; one end of a series circuit between a resistor R2 and an indicating lamp LED2 is connected with the negative of the DC power supply, and the other end of the series circuit is connected with a jack 4 of the socket CZ; and one end of a series circuit between a resistor R4 and a potentiometer W1 is connected with a jack 1 of the socket CZ, and the other end of the series circuit is connected with a jack 2 of the socket CZ through a switch K2. The test device and the tested temperature control box display synchronously to accurately adjust the control system of the temperature control box, so that the working temperature of the locomotive electric heating glass is controlled; the electric heating glass temperature control box test device is small in size and can be used in a fixed place and also in the locomotive.
Description
technical field [0001] The invention belongs to the technical field of diesel locomotives, and in particular relates to a test device for debugging the temperature of a temperature control box on the front window glass of a diesel locomotive. Background technique [0002] The electric heating glass for the front window of diesel locomotive is used for the driver to look out when working. There is one piece on the left and one on the left. When the weather is cold, the fog on the glass will hinder the driver's sight and affect driving safety. The fog on the glass must be removed. A temperature control box is installed on the front window glass of the diesel locomotive to remove the mist of the electric heating glass to ensure that the electric heating glass works within the range of 20°C to 25°C, and stops working when it is below 20°C or above 25°C. At present, the temperature working range of the temperature control box is directly loaded and debugged on the car, and the w...
