Description

Technical Field

[0001] The present application relates to the technical field of relay protection, and in particular to a detection device. Background Art

[0002] Relay protection is an important measure to detect faults or abnormal conditions in the power system, thereby issuing an alarm signal, or directly isolating and removing the faulty part. When in use, the protection device is often connected to the equipment for protection. When electrical equipment is in use, it often needs to be detected and processed by a detection device for subsequent use.

[0003] A Chinese patent with patent number CN218783575U discloses a relay protection detection device, which places a relay on a cushion block. The connecting wire of the device is first connected and fixed to a nearby leakage protector, and then passed through a wire trough to be connected and fixed to the corresponding contact point on the surface of the relay. The bolt is rotated to make the rubber pad drop to tightly press the wire to prevent the connection between the wire and the contact point from loosening and falling off due to dragging of the wire. The temperature of the contact point is measured in real time by a set infrared temperature sensor. When the current is too large and causes the relay to overload, the temperature of the contact point rises, and the set infrared temperature sensor can capture it in time, and the leakage protector automatically trips and cuts off the power to protect the relay, and ensure the safety of other electrical components connected to the relay.

[0004] However, during the placement of the relay, the relay is only placed on the pad. When the test box is hit, the relay will fall off the pad, thereby affecting the test effect and causing damage to the test data. Utility Model Content

[0014] Preferably, a relay protector for de-energizing the conductor is fixedly mounted on one side of the first sliding slot.

[0015] By adopting the above technical solution, the relay protector can quickly cut off the power supply after a problem occurs in the top conductor.

[0018] The present application provides a detection device. The beneficial effects are as follows:

[0019] 1. The detection device can effectively clamp and fix the relay placed in the detection box through the clamping components that can be pushed on both sides, so that the relay will not be affected when it is hit, so that the test can be carried out in a more stable state.
