SS-94 type time relay is used in the secondary circuit of power system relay protection and automatic control. It can be used as a delay element to make the controlled element achieve the required delay to realize the selective combination of protection and ensure the safe and reliable operation of the system.
This manual covers the SS-94 series of time relays, which are used as delay elements in secondary circuits of power system protection and automatic control. It describes the applicable range, model designations, and technical performance of each variant.
The document includes internal wiring diagrams, installation methods using AIIKK/AIIH/AIIQ housings, and ordering instructions that require model, rated voltage, and wiring style. It also lists delay ranges and step sizes for the different relay codes. This manual is written in Chinese.
| Delay range (code 1) | 20 ms – 9.999 s |
