IEC 61851-1 Pendulum Impact Test Apparatus For mechanical impact tests with PLC Control

Product Overview:

The Pendulum Impact Test Apparatus is designed and manufactured in full compliance with the following international and national standards:
GB/T 20138-2023, impact element requirements (referencing GB/T 2423.55-2023);
GB 7251.5-2017, Low-voltage switchgear and controlgear assemblies, Clauses 10.2.101.3 (Impact Load Test), 10.2.101.5 (Impact Resistance Verification Test), and 10.2.101.8 (Verification of Resistance to Mechanical Impact from Angular Objects);
GB/T 7251.4-2017, Clause 10.2.6.2 (Collision Test);
GB/T 39752-2021, Safety Requirements and Test Specifications for Electric Vehicle Supply Equipment;
EN IEC 61851-1:2019 / IEC 61851-1:2017;
GB/T 18663.1-2008, Cabinet Rigidity Test Requirements;
GB/T 20641-2014, General Requirements for Enclosures of Low-voltage Switchgear Assemblies;
GB 17467, Prefabricated High/Low-voltage Substations;
Q/GDW 11008.

It is mainly used for mechanical impact tests and related scientific research tests on low-voltage meter boxes, prefabricated substations, and electrical equipment casings. It can conveniently perform mechanical performance tests on metal meter boxes, non-metal meter boxes, cable distribution boxes, and other meter boxes of various specifications.

Application, Principle & Structure:

The Pendulum Impact Test Apparatus is suitable for performing:
Impact resistance verification,
Angular impact resistance verification,
Impact load verification,
Steel ball and sandbag impact tests for high and low-voltage switchgear, charging stations, and electrical cabinets.

Working Principle:

The test bench uses PLC intelligent central integrated control, touch screen display and operation, and can perform various impact tests on samples. Parameters are set via the touchscreen interface, and the test process is semi-automatic. The sample can be rotated for impact testing on all sides, accommodating a wide range of specimen sizes. It is the preferred reliability equipment for testing organizations and laboratories.

Structural Composition:

Elevation screw mechanism
Pendulum arm
Sample platform with rotation capability
Control console with integrated PLC and touch screen interface
