Problems solved by technology

The JP cabinet is prone to conduction after being exposed to moisture in rainy and snowy weather, which has great potential safety hazards and short service life.
Moreover, most of the JP cabinets are installed outdoors at present, and it is easy to be exposed to the sun and rain for a long time, which will cause the internal equipment of the JP cabinet to be damp and malfunction, and then a short circuit will cause a fire.
And installed in rural areas, the intelligence is not high, easy to be stolen

Embodiment Construction

[0022] The reactive power compensation unit adopts the capacitance compensation method, which can realize three-phase common compensation or phase split dynamic compensation. The common compensation capacitor adopts angle connection, and the split compensation capacitor adopts star connection. The common compensation is suitable for symmetrical loads, and the divided compensation is suitable for asymmetrical loads. or shock loads. The reactive power compensation unit has the basic protection function of overcurrent or quick break, and the switching switch achieves no contact, no inrush current, and no overvoltage. The compensation capacitor is a low-voltage self-healing or reactive capacitor. After the rated voltage of the capacitor is cut off, the residual voltage should be controlled below 50V within 3 minutes. When the network voltage exceeds the rated voltage by 1.2 times and is lower than the rated voltage by 0.85 times, the capacitor will be cut off immediately and refus...

Abstract

A JP cabinet is a distribution transformer comprehensive power distribution cabinet designed for meeting requirements of standardization, miniaturization and outdoor type of rural low-voltage power distribution equipment. The JP cabinet integrates power distribution, measurement, protection and capacitance reactive compensation. The JP cabinet can be affected with damp easily to conduct electricity when encountering rainy and snowy weathers, has great potential safety hazards, has a short service life, is low in intelligence and can be stolen easily. The invention relates to the field of electric equipment, and specifically provides a JP cabinet comprising a measurement monitoring incoming-line module, an electric energy distribution module, a reactive compensation module, a temperature control module, a fire protection module, an anti-theft module, a moisture-proof module, a GPRS (General Packet Radio Service) communication module, and an outgoing-line module. The JP cabinet provided by the invention can effectively prevent fire, theft and moisture, and achieves intelligent management control by virtue of communication between the GPRS communication module and a background power distribution management control system.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a JP cabinet. Background technique [0002] JP cabinet is a distribution transformer integrated distribution cabinet designed to meet the requirements of standardization, miniaturization and outdoor type of rural low-voltage power distribution equipment; it integrates power distribution, measurement, protection, and reactive power compensation of capacitors. The JP cabinet is prone to conduction after being damp in rainy and snowy weather, which has great potential safety hazards and short service life. Moreover, most of the JP cabinets are installed outdoors at present, and it is easy to be exposed to the sun and rain for a long time, which will cause the internal equipment of the JP cabinet to be damp and malfunction, and then a short circuit will cause a fire. And it is installed in rural areas, the intelligence is not high, and it is easy to be stolen. Contents of the i...
