Description

Technical Field

[0001] The utility model belongs to the technical field of circuit breakers, and in particular relates to a heat dissipation device for a test bench. Background Art

[0002] A circuit breaker refers to a switching device that can close, carry and disconnect current under normal circuit conditions and can close, carry and disconnect current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use, and the boundary between high and low voltage is relatively vague.

[0003] A Chinese patent with application number CN203643570U in the prior art discloses a circuit breaker action characteristic tester with a built-in power supply module for detecting the action characteristics of a circuit breaker. The circuit breaker action characteristic tester includes a circuit breaker action characteristic tester body, a power supply module is arranged inside the circuit breaker action characteristic tester body, and a power switch is arranged on the control panel of the circuit breaker action characteristic tester body. The power switch controls the conduction and disconnection of the power supply module and the circuit breaker action characteristic tester body. The power supply module provides direct current for closing the energy storage circuit breaker. The utility model has the advantages of easy carrying, simple line connection, and effectively reducing the workload of operators.

[0004] The working intensity of the tester is relatively high. Ordinary test benches are generally metal panels. Because the temperature of the tester is relatively high, the surface temperature of the test bench is also high. It is difficult to reduce the temperature during continuous operation. Long-term operation will affect the detection. For this reason, we propose a test bench heat dissipation device. Utility Model Content
