Static overcurrent relay JSL-10A series

Static overcurrent relay JSL-10A series


一、

Range and main functions

JSL static timing and limiting current relay for urban and rural power network power supply line, transformer, motor over load and short-circuit protection. Set startup, delay, the implementation of various AC operation static type multifunctional relay, with high precision, low power consumption, accurate delay, return coefficient is high, setting convenient and intuitive, contact capacity, no independent operation of the power characteristics for the relay. Is the GL type inverse time current relay and power network with fixed time protection should not be the substitute of graduation.

The relays are used, to AC operation opening and closing and high allocation of user medium do not resolve. Meet the power of the compressed time differential countermeasure, overcome the anti AC time for operation of the protection device and the power system timing protection does not match the fatal weakness, avoid the users because of the fault caused by the protection override trip into the surface of the expansion of the accident: using digital switch setting value of time limit protection, eliminating the original inverse time relay characteristic in the fixed value calculation, with superior and subordinate and debugging a large number of locks and complicated work, greatly convenient design and field work of employees as.

Two, the main technical parameters

The 1 part: current setting range: A:2.0-9.9A, 0.1A, B:10-50A; differential differential 1A.

2 overcurrent delay time setting range: 0.05-9.99S, differential: 0.01S (which is the current action time).

3 the setting range of the current speed breaking part: ISD=2.0-8.01GL.

4 current action time is not more than 50ms; specifications back with "T" logo of the quick break action time is 300ms. Setting error; part of an electrical current setting value error absolute value is not larger than 2%+0.1A; some of the time delay error absolute value not greater than 0.1%+10ms.

5 capacity: AC250V, can be connected to 16A long, closed contact can be diverted off the current AC>50A.

6: when the current consumption for the rated value, the relay power consumption is less than 5W.

7 thermal stability multiple: 2LH can run for a long time.

Three, terminal level and use instructions

JSL static timing and limiting current relay is updated products, alternative GL-10 series of inverse time current relay, therefore relay dimensions and wiring and GL-10 same. (see chart)
