Load cabinet

Product introduction

The device is designed and manufactured according to the relevant requirements of GB4943-2001, GB2099, GB16915.1, GB7000.1-2003, IEC60884, IEC61058, IEC60669.1 and other standards.

Scope of application:

Switches for household and similar fixed electrical installations are tested for on-off capability and normal operational life, as well as for breaking capacity and normal operational life testing of household and similar plugs and sockets.

parameter:

(1) Load cabinet function of plugs, sockets and non-fluorescent switches

u 1. When the single-phase electrical accessory load is used, the single-phase voltage of the load cabinet can be continuously adjusted within the range of 300V; when the three-phase electrical accessory load is used, the line voltage of the load cabinet can be continuously adjusted within the range of 500V; the single-phase load cabinet The rated current value is at least 40A, and the load current can be continuously adjusted within the rated value range, the total capacity is 30kVA, and the capacity of each channel is 10kVA;

u 2. The adjustable range of power factor includes at least 0.3-0.9. The resistor and inductor are not connected in parallel. The inductor in the load is a hollow inductor. To connect the resistor in parallel with the hollow inductor, the selected resistor should be able to consume 1% of the current flowing through the inductor.

u 3, with overcurrent protection and instantaneous short circuit protection;

u 4, can meet the three switches, plugs or socket products for the on-off capacity, breaking capacity or normal operation test;

u 5, the test of the three-pole electrical accessories to use a three-core inductor;

u 6, the steel part is stainless steel, the shell carbon steel paint. Anti-corrosion and rust prevention;

u 7. The equipment shall meet the wiring and test requirements for various plugs, sockets and non-fluorescent switches in GB2099.1-2008 and GB16915.1-2003.

(B), fluorescent lamp load cabinet function
