Abstract

The invention discloses a high-precision time delay, and belongs to the field of electrical equipment. According to the high-precision time delay, a power supply module, a storage module, a communication module, a switch, a crystal oscillator module, a reset module and a relay body are connected with a control module. The power supply module comprises a capacitor C1, a capacitor C2, a capacitor C3, a resistor R1, a Resistor R2, a resistor R3, a voltage-regulator tube DW1 and an electrical bridge. One end of the capacitor C1 is connected with a 220 v power source, and the other end of the capacitor C1 is connected with an electrical ridge input end. The resistor R1 is connected to the two ends of the capacitor C1 in a cramp joint mode. The two output ends of the electrical bridge are connected with the capacitor C2, the resistor R2, the resistor R3, the voltage-regulator tube DW1 and the capacitor C3 respectively. The capacitor C2, the resistor R2, the resistor R3, the voltage-regulator tube DW1 and the capacitor C3 are connected in parallel. Through improvement on the power supply module, the high-precision time delay is simple in structural line, small in delay error and high in accuracy. The time of the relay can be as precise as millisecond.

Description

technical field [0001] The invention relates to a time relay, specifically a high-precision time relay, belonging to the field of electrical equipment. Background technique [0002] The time relay refers to a kind of relay whose output circuit needs to pass through the specified accurate time to produce a jumping change (or contact action) after adding (or removing) the input action signal. The control system of the time relay is a very important component. The time relays in the prior art have large delay errors and low precision, and cannot meet specific application requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a time relay with small delay error and high precision. [0004] In order to solve the above-mentioned technical problems, the high-precision time relay provided by the present invention includes a control module, a power supply module, a st...
