Abstract
The invention discloses a high-voltage capacitor cabinet. The high-voltage capacitor cabinet is characterized in that only two locks can be unlocked in a designated sequence by using a key, so that the interlocking problem among a disconnecting switch, a vacuum contactor and a cabinet door is solved, thereby fail-safe safety requirements on the high-voltage capacitor cabinet are achieved.
Description
Technical field
The present invention relates to a kind of capacitor panel, especially a kind of high-voltage capacitor cabinet.
Background technology
A kind of high-voltage capacitor cabinet is characterized in that: through can only opening two locks by named order with a key, solving the interlocking problem between isolating switch ' straight empty contactor, the cabinet door, thereby reach " five is anti-" safety requirements of high-voltage capacitor cabinet.
Summary of the invention
To the problems referred to above, the present invention provides a kind of high-voltage capacitor cabinet.
High-voltage capacitor cabinet major loop is controlled meeting the people and withdrawing from of high-voltage capacitor by isolating switch, vacuum contactor forming control system.Need cabinet door, vacuum contactor, isolating switch be carried out interlocking.Guarantee (1) earlier disconnected vacuum contactor, draw isolating switch again, prevent that on-load from drawing isolating switch and causing the high-voltage arc short circuit; (2) only draw back isolating switch, just can open the cabinet door, prevent personnel's mistake people electrification in high voltage at interval, cause the accident; (3) when the cabinet door is opened, do not allow to close isolating switch, avoiding the introducing of high pressure to jeopardize personal safety has two kinds of conventional design:
(1) position switches on the isolating switch reaches when drawing isolating switch the purpose of earlier disconnected vacuum contactor; High-voltage charge display device (band locking type) is installed on the door; Electromagnetic lock is installed on the door.In the cabinet high pressure is arranged like this, display is bright. and reminds people has electricity, and simultaneously, electromagnetic lock is by locking, and it is higher that door just can not be opened this design element expense; Also to open two macropores on the door electrification display and electromagnetic lock are installed.When door was being opened, electromagnetic lock worked for a short time. the measure that isolating switch is not allowed combined floodgate of pinning must also will be arranged this moment.
(2) deciliter employing LW2 (KK) the conversion ON/OFF of vacuum contactor. carry out this design of program control with procedure lock (JSN) and can not use the push-botton operation vacuum contactor; To open
33mm macropore on the door procedure lock is installed; The whole operation step is very loaded down with trivial details, and expense is also high.Adopt " two locks, one key " scheme to solve the interlocking of high-voltage capacitor cabinet, its design feature: (1) cost is low, and expense is less than 10% of conventional design; (2) on the door without wide-bore; (3) can adorn later on, this is very convenient to installing additional of finished product; (4) all reach safety requirements.
