Embodiment Construction

[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] In order to make the 1E-class batteries of AP / CAP series nuclear power plants meet the battery load curve and the first-minute impact load requirements under the two working conditions of power failure and LOCA, and the installation space of 1E-class batteries is relatively narrow. Programming modular design ideas to design and manufacture DC load boxes.

[0029] 1. Appearance of programmable modular DC load box, such as figure 1 shown.

[0030] 2. The appearance of the combiner box, such as figure 2 shown.

[0031] 3. The programmable modular DC load box is mainly composed of electrical signal acquisition circuit, PLC control board, resistor array, CPU control board, protection circuit, remote communication circuit, so...

Abstract

The invention discloses a nuclear power station storage battery test direct current load device. The device comprises an electric signal acquisition loop, a PLC control panel, a resistor array, a CPUcontrol panel, a protection loop and a remote communication circuit. Through the modular design, the capacity of the whole set of direct current load box is increased to meet the load curve requirement of 72 hours or 24 hours and the severe-period high-current impact, and the load box can be freely combined according to the actual requirements of the site due to the fact that the size of the loadbox is reduced and the load box is convenient to carry. And the integration problem of a current and voltage acquisition and online monitoring system and a load box control system in the 1E-level storage battery test process is also solved.

Description

technical field [0001] The invention belongs to the technical field of storage battery debugging in nuclear power plants, and in particular relates to the performance verification technology of storage battery packs. Background technique [0002] For AP / CAP series nuclear power plants, in the case of plant power design basis accidents (the two working conditions of loss of AC power and LOCA in the whole plant), 1E-class battery packs can have 24h and 72h load curve carrying capacity according to different design requirements. In addition, the 1E-level battery packs of AP / CAP series nuclear power plants need to supply power to the 1E-class electric valves, and the starting current of the electric valves is relatively large (above 1200A), which requires the test device to be able to simulate the starting current of the electric valves to verify Carrying capacity during this harsh period. [0003] At present, the debugging devices and related tools of 1E-class batteries used i...
