Abstract
The utility model provides a comb-shaped aluminum alloy electric heater, which comprises a connecting terminal and a heating conductor. The utility model is characterized in that an indicating lamp is inserted in the connecting terminal; the indicating lamp is connected with a decompression assembly in series, and connected with the heating conductor in parallel. Through the indicating lamp of the comb-shaped aluminum alloy electric heater, the utility model can surveil and monitors work condition of input of the power supply, can judges whether the comb-shaped aluminum alloy electric heater works, and has simple structure.
Description
Technical field
The utility model relates to a kind of electric heater, relates in particular to a kind of switch cubicle electric heater.
Background technology
Pectination aluminium alloy electric heater is that the employing aluminium alloy extrusions is the heat loss through conduction body, for increasing area of dissipation, each fin has all designed wave groove, between fin and cover plate heating conductor is arranged, heating conductor is by resistance wire or metal PTC heat generating core, form with heatproof insulating materials such as micas, the resistance wire of heating conductor or metal PTC heat generating core are connected with binding post.Pectination aluminium alloy electric heater is applied to power equipment protection against the tide such as high and low voltage switch cabinet, mid-cabinet, terminal box, box-type substation, occasion is revealed in anti-freezing.At present, pectination aluminium alloy electric heater does not have indicator light, and whether whether it is normal to monitor and monitor the power supply input at any time, can not work from outer list deciding pectination aluminium alloy electric heater.
Summary of the invention
Whether technical problem to be solved in the utility model is to overcome the prior art defective, and a kind of pectination aluminium alloy electric heater is provided, can work from outer list deciding pectination aluminium alloy electric heater, and structure is very simple.
The technical scheme that technical problem adopted that the utility model solves is: pectination aluminium alloy electric heater, comprise binding post and heating conductor, and be characterized in that binding post is fixed with indicator light, indicator light series connection down block, in parallel with heating conductor.
The beneficial effects of the utility model are that whether by pectination aluminium alloy electric heater indicator light, it is normal to monitor and monitor the power supply input at any time, and judges whether pectination aluminium alloy electric heater works.
