Description
Technical field
The utility model relates to the security protection gate control system that a kind of protection for high-voltage test region and other places needing protective door to carry out electricity protection use.
Background technology
When carrying out high-voltage test to power equipment, tested device is needed to be placed on special region, keep apart with testing crew, perform region, after finishing test to equipment, testing crew needs deenergization, enters pilot region and changes tested device and wiring, in process of the test, special messenger's nurse is set, prevents other staff to be strayed into test site, in order to avoid get an electric shock; After off-test, testing crew just must can enter test site when cutting off experiment power supply, prevents from getting an electric shock.Once forget deenergization and enter test site, very serious electric shock accidents can be caused.
Summary of the invention
The purpose of this utility model is to propose a kind ofly to prevent testing crew in process of the test from just entering other staff in situation and process of the test that test site occurs to get an electric shock and be strayed into test site and get an electric shock not cutting off the electricity supply, and causes the security protection gate control system of personal injury and device damage.
The purpose of this utility model is achieved in that security protection gate control system, and it comprises fence for covering test site or enclosure wall, and in the inner, control desk position in the inner for test bench location.Described fence or enclosure wall offer import and export, imports and exports and door is installed.The application also comprises two power supplies, and wherein a power supply is as warning circuit, and another power supply, as hookup, described warning circuit is equiped with power knife switch, and this power knife switch is in normally off.Described power knife switch back-connected fuse, connects travel switch after fuse, meets warning lamp and A.C. contactor KM after travel switch.Another hookup it comprise testing table in parallel and control desk, aforementioned A.C. contactor KM connect testing table, between control desk and hookup.Test feed circuit are equiped with another power knife switch simultaneously, and this power knife switch is controlled closed by control desk.
Owing to implementing technique scheme, the utility model structure is simple, easy for installation, and material requested such as easily to purchase at the feature.The application arranges fuse and A.C. contactor simultaneously; while protection consumer; the automatic open close of circuit can be carried out; effectively prevent testing crew not cutting off the electricity supply just enters test site and other staff are strayed into test site; do not need to arrange special messenger's nurse, decrease crew numbers.
accompanying drawing explanation: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is that security protection gate control system circuit arranges schematic diagram.
Legend: QS: power knife switch; FU: fuse; SQ: travel switch; KM, KM1, KM2, KM3: A.C. contactor;
: warning lamp.
embodiment:
The utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, security protection gate control system it comprise fence for covering test site or enclosure wall, in the inner, control desk position is in the inner for test bench location.Described fence or enclosure wall offer import and export, imports and exports and door is installed.The application also comprises two power supplies, and wherein a power supply is as warning circuit, and another power supply, as hookup, described warning circuit is equiped with power knife switch, and this power knife switch is in normally off.Described power knife switch back-connected fuse, connects travel switch after fuse, meets warning lamp and A.C. contactor KM after travel switch.Another hookup it comprise testing table in parallel and control desk, aforementioned A.C. contactor KM connect testing table, between control desk and hookup.Test feed circuit are equiped with another power knife switch simultaneously, and this power knife switch is controlled closed by control desk.
Described travel switch is installed on the live wire L of warning circuit.
Described warning circuit and test feed circuit live wire L, zero line N on be all equiped with fuse.
In the doorframe that described travel switch is installed in import and export or door lock keyhole place, and be series on the live wire L of warning circuit.
Described warning lamp is in parallel with A.C. contactor KM.
During use, when the door imported and exported is opened, travel switch open circuit, warning circuit open circuit, warning lamp extinguishes, and A.C. contactor KM disconnects, and now control desk and test bench circuit disconnect, and staff can enter in test site and carry out track replacement.After replacing, shut the door of import and export, travel switch conducting, warning lamp is lighted, and now A.C. contactor KM closes, conduction test circuit, can carry out test next time.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
