Abstract
The utility model discloses a 400V low-voltage switch cabinet. The 400V low-voltage switch cabinet comprises a box body; one end of a rope is fixed at the outer side of the box body; the other end of the rope is connected with a test pencil; the test pencil comprises a conductive end and a display end; and the display end is coated with a transparent floating ball. After the test pencil is arranged at the outer side of the box body, if water level rises, and water is electrified, the test pencil will emit light to warn people that the water is electrified and they should not approach the water, and therefore, personal safety can be ensured; when the water level rises, the floating ball on the test pencil will float upwards with the rising of the water level, and therefore, the test pencil can be prevented from being flooded.
Description
Technical field
The utility model relates to a kind of switch cubicle, specifically 400V low-tension switch cabinet.
Background technology
Switch cubicle is a kind of electric equipment, and switch cubicle outside line is introduced into master switch in cabinet, then enters sub-control switch, and each shunt needs to arrange by it.As instrument, automatic control, motor magnetic switch, various A.C. contactors etc., what have also establishes hyperbaric chamber and low-pressure chamber switch cubicle, is provided with high voltage bus, and as power plant etc., what have is also provided with the low-frequency load reduction into protecting capital equipment.
The Main Function of switch cubicle is to generate electricity in electric power system, in the process of transmission of electricity, distribution and electric energy conversion, carry out folding, control and protection power consumption equipment.Parts in switch cubicle mainly contain the compositions such as circuit breaker, isolating switch, on-load switch, operating mechanism, instrument transformer and various protective devices.The sorting technique of switch cubicle is a lot, as being divided into withdraw-type switch cabinet and fixed switching cabinet by circuit breaker mounting means; Or according to the difference of cabinet body structure, can be divided into open type switch cubicle, metal closed switch cabinet and metal enclosed armoured switch cabinet; Can be divided into again high-tension switch cabinet, Medium Voltage Switchgear and low-tension switch cabinet etc. according to electric pressure difference.Mainly be applicable to various different occasions such as power plant, transformer station, petrochemical industry, metallurgical steel rolling, industry light industry textile industry, industrial enterprise and residential quarters, skyscraper etc.
Damage to switch cubicle internal electric equipment when existing switch cubicle generally all cannot be defendd to flood, and in the time that ponding is arranged at switch cubicle bottom, just in case switch cubicle has electric leakage, so can be charged in water, can cause unexpected injury just in case there is people to pass through ponding place.
Summary of the invention
The utility model, for prior art deficiency, provides 400V low-tension switch cabinet, and this switch cubicle can detect ponding in the time of the ponding of switch cubicle bottom, prevents from that ponding is charged people is damaged.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
400V low-tension switch cabinet, comprises casing, and one end of rope is fixed in described casing outside, and the other end of described rope is connected with test pencil, and described test pencil comprises conducting end and display end, and described display end is coated in transparent ball float.After casing arranged outside test pencil, if have electricity in water in the time that water level goes up, test pencil will have electricity beyond this point in shinny prompting people water so, ensure personal safety, and when water level goes up, the ball float on test pencil can up float along with water level goes up, and prevents that water logging from there not being test pencil, and owing to being rope traction, therefore the height that ball float rises is as long as rope long enough just can infinitely raise, and irrelevant with the height of switch cubicle, no matter large-scale small-sized switch cubicle can use.
In technique scheme, preferred, in the conducting end of described test pencil, be provided with weight.Weight is set makes conducting end can touch all the time water down.
The utility model compared with prior art, has following beneficial effect:
The utility model is after casing arranged outside test pencil, if have electricity in water in the time that water level goes up, test pencil will have electricity beyond this point in shinny prompting people water so, ensure personal safety, and the ball float when water level goes up on test pencil can up float along with water level goes up, and prevents that water logging from there not being test pencil.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 1,400V low-tension switch cabinet, comprise casing 1, one end of rope 2 is fixed in described casing 1 outside, the other end of described rope 2 is connected with test pencil 3, described test pencil 3 comprises conducting end 31 and display end 32, and described display end 32 is coated in transparent ball float 4.After casing 1 arranged outside test pencil 3, if have electricity in water in the time that water level goes up, test pencil 3 will have electricity beyond this point in shinny prompting people water so, ensure personal safety, and the ball float 4 when water level goes up on test pencil 3 can up float along with water level goes up, prevent that water logging from there not being test pencil 3, and owing to being rope traction, therefore the height that ball float 4 rises is as long as rope 2 long enoughs just can infinitely raise, height with switch cubicle is irrelevant, and no matter large-scale small-sized switch cubicle can use.
In the process that ensures to rise and decline at ball float 4, the conducting end 31 of test pencil 3 touches water all the time down, in the conducting end 31 of described test pencil 3, is provided with weight 33.
Claims (2)
1.400V low-tension switch cabinet, comprise casing (1), it is characterized in that: one end of rope (2) is fixed in described casing (1) outside, the other end of described rope (2) is connected with test pencil (3), described test pencil (3) comprises conducting end (31) and display end (32), and described display end (32) is coated in transparent ball float (4).
2. 400V low-tension switch cabinet as claimed in claim 1, is characterized in that: in the conducting end (31) of described test pencil (3), be provided with weight (33).
